Replacing symt_get_inlinesite_depth() with SymAddrIncludeInlineTrace()
as they look very (very) similar.

Basically:
- extending symt_function to enable storage of multiple address ranges
- symt_function and sym_inlinesite now share the same fields, so
get rid to the later.
Note that only the first range of a top level function is actually
stored and used (even if the structure allows for more).

Instead of silently leaking no longer used chunks.
Be more robust to OOM conditions.
Introducing pool_realloc().
Signed-off-by: Eric Pouech <eric.pouech@gmail.com>
Rationale:
- native doesn't report names for SymTagBaseType objects
=> so remove typename for sym_basic
- since symt_basic becomes pretty simple, it's possible to share the object
across all modules loaded in dbghelp (simplicity, memory usage reduction)
- removed dwarf basic types cache in dwarf.c as we now have a generic one

To be used in place of symt_find_nearest().
symt_find_symbol_at() ensures that the address passed is within the
boundaries of the returned symbol (while find_nearest() doesn't).
This fixes erroneous backtraces in debugger like:

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

Since with the unknown type entry, we can end up with types which don't
match the expected symt->tag, we need to check before the conversions.

SYMBOL_INFO.NameLen should be the actual length of the symbol, not the
length of the (potentially truncated) string returned in
