---
-- This module was written to marshall parameters for Microsoft RPC (MSRPC) calls. The values passed in and out are based
-- on structs defined by the protocol, and documented by Samba developers. For detailed breakdowns of the types, take a
-- look at Samba 4.0's <code>.idl</code> files.
--
-- There is nothing simple about how this all comes together, so I'll take some time to explain how it's done. This
-- is fairly technical and, when it comes right down to it, unnecessary for how to use these functions (although if you
-- want to write one of these, you best understand it).
--
-- There are base types, like int32 and int16. These are marshalled the way you'd expect (converted to a 4- or
-- 2-byte little endian string). The only trick with these is that they have to end up aligned on 4-byte boundaries.
-- So, a 2-byte integer requires 2 bytes of padding, and a 1-byte integer requires 3 bytes of padding. The functions
-- <code>marshall_int32</code>, <code>marshall_int16</code>, etc. will marshall the base types, and <code>unmarshall_int32</code>,
-- <code>unmarshall_int16</code>, etc. will unmarshall them.
--
-- Strings are a little bit trickier. A string is preceded by three 32-bit values: the max length, the offset, and
-- the length. Additionally, strings may or may not be null terminated, depending on where they're being used. For
-- more information on strings, see the comments on <code>marshall_unicode</code>. The functions <code>marshall_unicode</code>
-- and <code>unmarshall_unicode</code> can be used to mashall/unmarshall strings.
--
-- Pointers also have interesting properties. A pointer is preceeded by a 4-byte value called (at least by Wireshark)
-- the "referent id". For a valid pointer, this can be anything except 0 (I use 'NMAP' for it). If it's '0', then
-- it's a null pointer and the data doesn't actually follow. To help clarify, a pointer to the integer '4' could be
-- marshalled as the hex string <code>78 56 34 12 04 00 00 00</code> (the referent_id is 0x12345678 and the integer
-- itself is 0x00000004). If the integer is nil, then it's marshalled as <code>00 00 00 00</code>, which is simply
-- a referent_id of 0.
--
-- From the perspective of the program, pointers can be marshalled by using the "<code>_ptr</code>" versions of normal functions
-- (for example, <code>marshall_int32_ptr</code> and <code>unmarshall_unicode_ptr</code>. From the perspective
-- of functions within this module, especially functions for marshalling structs and arrays, the <code>marshall_ptr</code>
-- and <code>unmarshall_ptr</code> functions should be used. These can marshall any data type; the marshalling function
-- is passed as a parameter.
--
-- So far, this is fairly straight forward. Arrays are where everything falls apart.
--
-- An array of basic types is simply the types themselves, preceeded by the "max length" of the array (which can be
-- longer than the actual length). When pointers are used in an array, however, things get hairy. The 'referent_id's
-- of the pointers are all put at the start of the array, along with the base types. Then, the data is put at the
-- end of the array, for all the referent_ids that aren't null. Let's say you have four strings, "abc", "def", null, and
-- "jkl", in an array. The array would look like this:
-- <code>
-- 0x00200000 (referent_id for "abc")
-- 0x00400000 (referent_id for "def")
-- 0x00000000 (null referent_id)
-- 0x00800000 (referent_id for "jkl")
-- "abc" (note that this also has the standard string stuff, the max_length, offset, and actual_length)
-- "def"
-- "ghi"
-- </code>
--
-- If you mix in a base type, it goes at the front along with the referent_ids. So, let's say you have a structure
-- that contains two integers and a string. You have an array of these. It would encode like this:
-- <code>
-- 0x00200000 (referent_id for the string in the first struct)
-- 0x00000001 (first integer in the first struct)
-- 0x00000002 (second integer in the first struct)
-- 0x00400000 (referent_id for the string in the second struct)
-- 0x00000003 (first integer in the second struct)
-- 0x00000004 (second integer in the second struct)
-- "string1" (contains max_length, offset, and actual_length)
-- "string2"
-- </code>
--
-- From the perspective of the program, arrays shouldn't need to be marshalled/unmarshalled, this is tricky and should be
-- left up to functions within this module. Functions within this module should use <code>marshall_array</code> and
-- <code>unmarshall_array</code> to interact with arrays. These take callback functions for the datatype being stored
-- in the array; these callback functions have to be in a particular format, so care should be taken when writing them.
-- In particular, the first parameter has to be <code>location</code>, which is used to separate the header (the part with the
-- referent_ids) and the body (the part with the pointer data). These are explained more thoroughly in the function headers.
--
-- Structs are handled the same as arrays. The referent_ids and base types go at the top, and the values being pointed to
-- go at the bottom. An array of struct, as has already been shown, will have all the base types and referent_ids for all the
-- members at the top, and all the values for all the pointers at the bottom.
--
-- Structs tend to be custom functions. Sometimes, these functions are passed as the callback to <code>marshall_ptr</code> or
-- <code>marshall_array</code> (and the equivalent <code>unmarshall_</code> functions). This means that the custom struct
-- functions have to be able to split themselves into the base types and the pointer data automatically. For an example, see
-- the functions that have already been written.
--
-- In the case where you need to unmarshall the same struct from both an array and a pointer, there's an issue; they require
-- different prototypes. There's really no way to directly fix this, at least, none that I could come up with, so I write
-- a function called <code>unmarshall_struct</code>. <code>unmarshall_struct</code> basically calls a struct unmarshalling
-- function the same way <code>unmarshall_array</code> would. This is a bit of a kludge, but it's the best I could come up
-- with.
--
-- There are different sections in here, which correspond to "families" of types. I modelled these after Samba's <code>.idl</code> files.
-- MISC corresponds to <code>misc.idl</code>, LSA to <code>lsa.idl</code>, etc. Each of these sections has possible dependencies; for example, SAMR
-- functions use LSA strings, and everything uses SECURITY and MISC. So the order is important -- dependencies have to go
-- above the module.
--
-- The datatypes used here are modelled after the datatypes used by Microsoft's functions. Each function that represents
-- a struct will have the struct definition in its comment; and that struct (or the closest representation to it) will be
-- returned. Often, this requires scripts to access something like <code>result['names']['names'][0]['name']</code>, which is
-- rather unwieldy, but I decided that following Microsoft's definitions was the most usable way for many reasons. I find
-- the best way to figure out how to work a function is to call a print_table()-style function on the result and look at
-- how the response is laid out.
--
-- Many datatypes are automatically encoded when sent and decoded when received to make life easier for developers. Some
-- examples are:
-- * All absolute time values will be seconds from 1970
-- * All relative time values will be in seconds (this includes the <code>hyper</code> datatype); when possible, the milliseconds/microseconds (as far down as we have access to) will be preserved as a decimal
-- * All enumerations will be a string representing the constant (which can be converted to a user-readable string using one of the <code>_tostr</code> functions); what that means is, enumeration values are never used, only the names
-- * SIDs will be converted to user-readable strings in the standard format (S-x-y-...)
-- * GUIDs are stored as tables of values; however, I might change this to a string representation at some point

---Marshalls a pointer to another datatype. This function will optionally separate the
-- REFERENT_ID of the pointer (which goes at location = HEAD) from the data part of the
-- pointer (which goes at location = BODY). If the entire pointer is needed, then location
-- should be set to ALL.
--
-- When marshalling the body, the function <code>func</code> is called, which is passed as
-- a parameter, with the arguments <code>args</code>. This function has to return a marshalled
-- parameter, but other than that it can be any marshalling function. The 'value' parameter
-- simply determined whether or not it's a null pointer, and will probably be a repease of
-- one of the arguments.
--
-- Note that the function <code>func</code> doesn't have to conform to any special prototype,
-- as long as the <code>args</code> array matches what the function wants.
--
-- This can be used to marshall an int16 value of 0x1234 with padding like this:
-- <code>
-- marshall_ptr(ALL, marshall_int16, {0x1234, true}, 0x1234)
-- </code>
--
-- And here's how a 'nil' string might be marshalled:
-- <code>
-- local str = nil
-- marshall_ptr(ALL, marshall_unicode, {str, true}, str)
-- </code>
--
--@param location The part of the pointer wanted, either HEAD (for the referent_id), BODY
-- (for the pointer data), or ALL (for both together). Generally, unless the
-- referent_id is split from the data (for example, in an array), you will want
-- ALL.
--@param func The function to call when encoding the body. Should convert the arguments passed
-- in the <code>args</code> parameter to a string.
--@param args An array of arguments that will be directly passed to the function <code>func</code>
--@param value The value that's actually being encoded. This is simply used to determine whether or
