Remove a memory leak.

Fix heap overflow caused by not accounting for the dummy first item,
which contains the codepage.

Move the uninitialized apartment check after zeroing out the return
value.

ECO_READONLY implemented and tested.

Fix up encoded data to use BYTE arrays rather than strings, and remove
extraneous NULL bytes from the end of some of them

Move CryptVerifyMessageSignature stub to main.c.

since ImagePathName is not always set at that point.

and make it compatible with the way other options are stored.

to represent load order values.
Added a special value for default load order so that we can handle it
differently later on.

FT_Module_Get_Flags existed briefly in freetype 2.2.0.rc1 but has now
been replaced by FT_Get_TrueType_Engine_Type.  There's no point in
supporting an rc1 release, so this removes support for
FT_Module_Get_Flags and adds support for FT_Get_TrueType_Engine_Type.

It seems like the esp value (which is saved at [ebp-16]) is sometimes
changed inside the catch handler so we end up with a bogus esp
afterwards.  To avoid that save it before calling the catch block.

Save in each nested frame a pointer to the original exception record.
Only one refence in thread_data isn't enough when we have multiple
nested frames.

Move handling of nested exceptions completely in the
catch_function_nested_handler().  If a new exception was thrown inside
a catch block destroy the old exception object, if it is a rethrow
re-propagate the previous object.

- read strings from left to right (PathGetDriveNumberW)
- don't access buffers before they are filled (SHGetPathFromIDListW)
- fill buffers & variables on all paths (SHELL_FindExecutable)
- handle error condition (unix_fs)
- don't shoot in the blind for AW APIs (tests/shelllink.c)

Add some missing MAPI prototypes to mapi.h (spotted by winapi_check)
and include it where they are implemented.
Make mapi.h and mapix.h compatible. gcc does not like macros and
prototypes to be redefined so this involved protecting against
multiple definitions.
Fix the MAPISendMail() implementation prototype.
