(actually the dwarf2_parse_context should be named dwarf2_parse_cu_context

the rationale is that:
- the file name in IMAGEHLP_LINE* structures is returned as a pointer to
an internal buffer
- in the W64 variant of APIs, two calls to fetch_buffer() are currently needed
(one for first A allocation, second for W conversion)
- this generate bugs as it's assumed the two buffers are different
so the internal_line_t purpose is to factorize the implementations
of the 3 variants (A32, A64, W64) into a single code path
this insures a unique allocation, and at most, one conversion

use case, in a WoW setup:
wine programs/winedbg/winedbg.exe.so notepad.exe
where both winedbg and notepad are 64bit exec:s
in this case, dbghelp (loaded from winedbg) reads '<...>/wine' from WINELOADER
windows env block inside notepad
(but the unix env block is correctly set to wine64 by the tweak in
ntdll/unix/loader.c)
as a consequence dbghelp doesn't get the ELF information (it tries to read 32bit
ELF entities, and fails); hence misses all the loaded ELF libraries
winedbg's command 'info share' only reports the PE modules
note: the 'dual' case
wine64 programs/winedbg/winedbg.exe.so c:\\windows\\syswow64\\notepad.exe
where winedbg is a 64bit exec and notepad a 32bit
shows the same failures
workaround this in dbghelp by tweaking the value of WINELOADER whether
the debuggee is 32 or 64bit
