- moved into new mscvpdb.h (out of msc.c) all types and defines needed

to parse debug files generated by MS tools - moved into coff.c (and out of msc.c) the COFF handling - cleaned lots of types (add consistency across structs) - versioning of some defines and types (to follow MS tools evolution) - enhanced V2 of symbols parsing (some more types recognized, support of imported .pdb files) - added support for newest .pdb format

/* MS has stored all its debug information in a set of structures
* which has been rather consistent across the years (ie you can grasp
* some continuity, and not so many drastic changes).
*
* A bit of history on the various formats
* MSVC 1.0 PDB v1 (new format for debug info)
* MSVC 2.0 Inclusion in link of debug info (PDB v2)
* MSVC 5.0 Types are 24 bits (instead of 16 for <= 4.x)
* MSVC x.0 PDB (change in internal streams layout)
*
* .DBG Contains COFF, FPO and Codeview info
* .PDB New format for debug info (information is
* derived from Codeview information)
* VCx0.PDB x major MSVC number, stores types, while
* <project>.PDB stores symbols.
*
* Debug information can either be found in the debug section of a PE
* module (in something close to a .DBG file), or the debug section
* can actually refer to an external file, which can be in turn,
* either a .DBG or .PDB file.
*
* Regarding PDB files:
* -------------------
* They are implemented as a set of internal files (as a small file
* system). The file is split into blocks, an internal file is made
* of a set of blocks. Internal files are accessed through
* numbers. For example,
* 1/ is the ROOT (basic information on the file)
* 2/ is the Symbol information (global symbols, local variables...)
* 3/ is the Type internal file (each the symbols can have type
* information associated with it).
*
* Over the years, three formats existed for the PDB:
* - ?? was rather linked to 16 bit code (our support shall be rather
* bad)
* - JG: it's the signature embedded in the file header. This format
* has been used in MSVC 2.0 => 5.0.
* - DS: it's the signature embedded in the file header. It's the
* current format supported my MS.
*
* Types internal stream
* ---------------------
* Types (from the Type internal file) have existed in three flavors
* (note that those flavors came as historical evolution, but there
* isn't a one to one link between types evolution and PDB formats'
* evolutions:
* - the first flavor (suffixed by V1 in this file), where the types
* and subtypes are 16 bit entities; and where strings are in Pascal
* format (first char is their length and are not 0 terminated)
* - the second flavor (suffixed by V2) differs from first flavor with
* types and subtypes as 32 bit entities. This forced some
* reordering of fields in some types
* - the third flavor (suffixed by V3) differs from second flavor with
* strings stored as C strings (ie are 0 terminated, instead of
* length prefixed)
* The different flavors can coexist in the same file (is this really
* true ??)
*
* For the evolution of types, the need of the second flavor was the
* number of types to be defined (limited to 0xFFFF, including the C
* basic types); the need of the third flavor is the increase of
* symbol size (to be greated than 256), which was likely needed for
* complex C++ types (nested + templates).
*
* It's somehow difficult to represent the layout of those types on
* disk because:
* - some integral values are stored as numeric leaf, which size is
* variable depending on its value
*
* Symbols internal stream
* -----------------------
* Here also we find three flavors (that we've suffixed with _V1, _V2
* and _V3) even if their evolution is closer to the evolution of
* types, there are not completly linked together.
