Eric Pouech 812b4b1ca3 dbghelp: Use source file path as stored in debug info format. 
Currently, dbghelp returns the source file either:
- in DOS format when native module option isn't enabled
- as stored in debug info format otherwise

This used to work for PE modules inside ELF shared libraries but is broken
since evolution to REAL modules. This generates several issues:
- winedbg does not always set the native module option when calling dbghelp
  for source file related functions, leading to heterogenous output to user
- some dbghelp function rely on matching source paths, hence leading to
  errors in winedbg when mixing the two formats for the same source file.

Introduce a new Wine only dbghelp option to return the source paths as they
are stored inside debug information format, and activate it unconditionaly
inside winedbg.

This fixes some failure cases of command 'break <NN>' in winedbg.

/* TODO list:
*
* - minidump
* + ensure that all commands work as expected in minidump reload function
* (and re-enable parser usage)
* - CPU adherence
* + we always assume the stack grows as on i386 (i.e. downwards)
* - UI
* + re-enable the limited output (depth of structure printing and number of
* lines)
* + make the output as close as possible to what gdb does
* - symbol management:
* + symbol table loading is broken
* + in symbol_get_lvalue, we don't do any scoping (as C does) between local and
* global vars (we may need this to force some display for example). A solution
* would be always to return arrays with: local vars, global vars, thunks
* - type management:
* + some bits of internal types are missing (like type casts and the address
* operator)
* + all computations should be made on 64bit
* o bitfield spreading on more bytes than dbg_lgint_t isn't supported
* (can happen on 128bit integers, of an ELF build...)
* - execution:
* + set a better fix for gdb (proxy mode) than the step-mode hack
* + implement function call in debuggee
* + trampoline management is broken when getting 16 <=> 32 thunk destination
* address
* + thunking of delayed imports doesn't work as expected (ie, when stepping,
* it currently stops at first insn with line number during the library
* loading). We should identify this (__wine_delay_import) and set a
* breakpoint instead of single stepping the library loading.
* + it's wrong to copy thread->step_over_bp into process->bp[0] (when
* we have a multi-thread debuggee). complete fix must include storing all
* thread's step-over bp in process-wide bp array, and not to handle bp
* when we have the wrong thread running into that bp
* + code in CREATE_PROCESS debug event doesn't work on Windows, as we cannot
* get the name of the main module this way. We should rewrite all this code
* and store in struct dbg_process as early as possible (before process
* creation or attachment), the name of the main module
* - global:
* + define a better way to enable the wine extensions (either DBG SDK function
* in dbghelp, or TLS variable, or environment variable or ...)
* + audit all files to ensure that we check all potential return values from
* every function call to catch the errors
* + BTW check also whether the exception mechanism is the best way to return
* errors (or find a proper fix for MinGW port)
