Greg Clayton 8087ca2160 Added mutex protection to the Symtab class.
Added a new SortOrder enumeration and hooked it up to the "image dump symtab"
command so we can dump symbol tables in the original order, sorted by address, 
or sorted by name.

Greg Clayton 8941142af8 Hooked up ability to look up data symbols so they show up in disassembly
if the address comes from a data section. 

Fixed an issue that could occur when looking up a symbol that has a zero
byte size where no match would be returned even if there was an exact symbol
match.

Cleaned up the section dump output and added the section type into the output.

Greg Clayton f5e56de080 Moved the section load list up into the target so we can use the target
to symbolicate things without the need for a valid process subclass.

Greg Clayton 0c38b0deb8 Fixed an issue I found in the mach-o symbol table parsing where
we cached remapping information using the old nlist index to the
new symbol index, yet we tried to lookup the symbol stubs that
were for symbols that had been remapped by ID instead of using
the new symbol index. This is now fixed and the mach-o symbol tables
are fixed.

Use the delta between two vector entries to determine the stride
in case any padding is inserted by compilers for bsearch calls
on symbol tables when finding symbols by their original ID.

Greg Clayton bcf2cfbdc5 Remove the eSymbolTypeFunction, eSymbolTypeGlobal, and eSymbolTypeStatic.
They will now be represented as:
eSymbolTypeFunction: eSymbolTypeCode with IsDebug() == true
  eSymbolTypeGlobal: eSymbolTypeData with IsDebug() == true and IsExternal() == true
  eSymbolTypeStatic: eSymbolTypeData with IsDebug() == true and IsExternal() == false

This simplifies the logic when dealing with symbols and allows for symbols
to be coalesced into a single symbol most of the time.

Enabled the minimal symbol table for mach-o again after working out all the
kinks. We now get nice concise symbol tables and debugging with DWARF in the
.o files with a debug map in the binary works well again. There were issues
where the SymbolFileDWARFDebugMap symbol file parser was using symbol IDs and
symbol indexes interchangeably. Now that all those issues are resolved 
debugging is working nicely.

Greg Clayton 49bd1c847b Added Symtab::FindSymbolByID() in preparation for enabling the minimal
symbol tables. Minimal symbol tables enable us to merge two symbols, one
debug symbol and one linker symbol, into a single symbol that can carry
just as much information and will avoid duplicate symbols in the symbol
table.

Greg Clayton 471b31ce62 Remove use of STL collection class use of the "data()" method since it isn't
part of C++'98. Most of these were "std::vector<T>::data()" and 
"std::string::data()".

Greg Clayton 044672b076 Logic fix to properly determine when a symbol is not from the current
symbol table (from William Lynch).

Owen Anderson c7da5f413b Switch from qsort_r to std::stable_sort for a performance win and improved portability.

Owen Anderson 571e864e84 Revert my previous patch. Apparently the code-size impact of std::sort isn't acceptable.

Owen Anderson dc433611a2 Replace qsort_r with std::sort. This gets rid of a lot of portability
ickiness, and is cleaner to boot.

I'm fairly confident that I converted the comparator over properly,
and what testing I could figure out how to run seemed to pass, but it
would be great if someone in the know could check behind me.

Eli Friedman a92e332b09 Make qsort_r usage "portable". Why does a function which seems so simple
have to be so complicated?
