[PATCH v2] winedbg: Try to load debug symbols for executable in gdb mode.

[Bernhard Übelacker]

Signed-off-by: Bernhard Übelacker 
----
This loads the debug information similar to
LOAD_DLL_DEBUG_EVENT for dll's a few lines below, or
CREATE_PROCESS_DEBUG_EVENT for exe's in winedbg/tgt_active.c.

It should be an improvement just for real PE executables.

For .exe.so files the debug information gets loaded via the ELF
enumeration, with this patch 'info share' shows a line for
the fake exe additional to the .exe.so line.

Resend:

v2:
- Removed fetch_module_name and logging.
