Alex Brainman 497d114ce9 debug/pe: use ws2_32.dll in TestImportTableInUnknownSection
Apparently (see
https://github.com/golang/go/issues/27904#issuecomment-442140627
for details) kernel32.dll file is not present on windows/arm, so
use ws2_32.dll instead. ws2_32.dll imports table also lives in
'.rdata' section, so ws2_32.dll is as good as kernel32.dll for
testing issue #16103.

Updates #27904

Alex Brainman e7eabeb4ba debug/pe: correct TestImportTableInUnknownSection error message
TestImportTableInUnknownSection uses kernel32.dll file, but the error
message mentions atmfd.dll. Adjust error message to match the test.

This change should have been part of CL 151137.

Alex Brainman 0d87393ea3 debug/pe: use kernel32.dll in TestImportTableInUnknownSection
TestImportTableInUnknownSection was introduced in CL 110555 to
test PE executable with import table located in section other than
".idata". We used atmfd.dll for that purpose, but it seems
atmfd.dll is not present on some systems.

Use kernel32.dll instead. kernel32.dll import table is located in
".rdata" section, so it should do the job. And every Windows
system has kernel32.dll file.

Also make TestImportTableInUnknownSection run on windows-arm,
since windows-arm should also have kernel32.dll file.

Alex Brainman 1f209b4401 cmd/link: actually generate .debug_gdb_scripts section on windows
Adjust finddebugruntimepath to look for runtime/debug.go file
instead of runtime/runtime.go. This actually finds runtime.GOMAXPROCS
in every Go executable (including windows).

I also included "-Wl,-T,fix_debug_gdb_scripts.ld" parameter to gcc
invocation on windows to work around gcc bug (see #20183 for details).

This CL only fixes windows -buildmode=exe, buildmode=c-archive
is still broken.

Thanks to Egon Elbre and Nick Clifton for investigation.

Fixes #20183
Fixes #20218

Alex Brainman 7c2bfbf0a9 debug/pe: handle files with no string table
pecoff.doc (https://goo.gl/ayvckk) in section 5.6 says:

Immediately following the COFF symbol table is the COFF string table.
The position of this table is found by taking the symbol table address
in the COFF header, and adding the number of symbols multiplied by
the size of a symbol.

So it is unclear what to do when symbol table address is 0.
Lets assume executable does not have any string table.

Added new test with executable with no symbol table. The

gcc -s testdata\hello.c -o testdata\gcc-386-mingw-no-symbols-exec.

command was used to generate the executable.

Alex Brainman fabea0ed5a debug/pe: unexport newly introduced identifiers
CLs 22181, 22332 and 22336 intorduced new functionality to be used
in cmd/link (see issue #15345 for details). But we didn't have chance
to use new functionality yet. Unexport newly introduced identifiers,
so we don't have to commit to the API until we actually tried it.

Rename File.COFFSymbols into File._COFFSymbols,
COFFSymbol.FullName into COFFSymbol._FullName,
Section.Relocs into Section._Relocs,
Reloc into _Relocs,
File.StringTable into File._StringTable and
StringTable into _StringTable.

Alex Brainman 7bfbb36f3f debug/pe: introduce File.COFFSymbols and (*COFFSymbol).FullName
Reloc.SymbolTableIndex is an index into symbol table. But
Reloc.SymbolTableIndex cannot be used as index into File.Symbols,
because File.Symbols slice has Aux lines removed as it is built.

We cannot change the way File.Symbols works, so I propose we
introduce new File.COFFSymbols that does not have that limitation.

Also unlike File.Symbols, File.COFFSymbols will consist of
COFFSymbol. COFFSymbol matches PE COFF specification exactly,
and it is simpler to use.
