Tobias Brunner 21af89f941 backtrace: Add ability to lookup function names via libbfd 
dladdr() is not always able to determine the function names while
libbfd often can in such cases.

Tobias Brunner 2bf110d9f8 backtrace: Fix build with newer MinGW versions 
A recent change added CALLBACK to PENUM_PAGE_FILE_CALLBACKW/A in psapi.h,
which conflicts with our own macro of the same name.  Our compat/windows.h
header undefs the Windows definition, but that only works if Windows
headers are included before ours, which wasn't the case for psapi.h.

Martin Willi 2127831cda backtrace: Support backtraces on Windows without DbgHelp 
While DbgHelp provides a convenient API to create backtraces, any executable
linking against DbgHelp gets a more than a significant slow down. Further, it
can only lookup global symbols, as it expects PDB files we can't produce with a
MinGW build.

With some core Kernel32.dll functionality, we can capture stack traces much
faster. Together with the optional libbfd, we can print very fine backtraces.

When --enable-bfd-backtraces is used on Windows, a libbfd.dll is required for
the build. Such a DLL can be created from the binutils sources using:

  # build binutils with mingw...

  # extract archive members from binutils libraries
  x86_64-w64-mingw32-ar x $BINUTILS/bfd/.libs/libbfd.a
  x86_64-w64-mingw32-ar x $BINUTILS/intl/libintl.a
  x86_64-w64-mingw32-ar x $BINUTILS/libiberty/libiberty.a

  # create self-contained libbfd.a, with index
  x86_64-w64-mingw32-ar qs libbfd.a *.o

  # create DLL from static library
  x86_64-w64-mingw32-dlltool -e libbfd.o -l libbfd.lib libbfd.a
  x86_64-w64-mingw32-gcc -shared libbfd.a libbfd.o -o libbfd.dll

Martin Willi 4c6c934635 With --enable-bfd-backtraces, use binutils libbfd to resolve backtraces 
The invocation of addr2line to resolve backtrace source locations
is slow and cumbersome. When using libbfd directly, we can eliminate
the overhead of the process invocation. Even better, we can cache
library symbol names, bringing wicked fast lookups. As a neat bonus,
we can resolve static function names.
