Install headers and pkg-config files

Installing a library without headers or pkg-config file isn't much use

See http://code.google.com/p/google-breakpad/issues/detail?id=219

v2:
Remove --with-pkgconfigdir option, just use $(libdir)/pkgconfig
Use $(includedir) rather than $(prefix)/include
Avoid O_BINARY redefinition warning on Cygwin

On Cygwin, WIN32 not defined, but O_BINARY is defined by fcntl.h, so avoid a
redefinition warning.

Build minidump_upload, sym_upload for all targets

Rather than duplicating these tools for any target which has libcurl
- Introduce src/tools/common/ and move minidump_upload, sym_upload there from src/tools/linux/
- Move linux/http_upload.cc,.h up to src/common/ from src/common/linux/

Don't link with -ldl and use dlopen to use libcurl.so, but just link with
libcurl.

XXX: Perhaps retaining linking with -dl and just teaching it the name of curl
shared object on Cygwin would be more upstreamable, although the reasons for not
linking with libcurl are obscure...
Remove local copy of curl headers

This reverts commit d9d863e153d12532fc85bd8b44bc47f079ed064c.
This reverts commit 68e380d5a73a0d657693f166fbcb1dd77027766b.
Add support for DWARF in PECOFF as used by Cygwin and MinGW

For cygwin and mingw targets, build a dump_syms tool which can read DWARF
symbols contained in a PE/COFF executable.

I felt bad about making another copy of dump_symbols.cc, so this one has the
beginnings of being parameterized by an image file reader class, so we can apply
it to a pecoff-format image file reading class

Write pecoff format image file reading class which
- knows how to read PE32 and PE32+ image files
- makes PECOFF file id by fetching from a CV record or by hashing
- can read PECOFF exports as a fallback if there is no DWARF information

v2:
Don't include arpa/inet.h on MinGW

v3:
Use AM_CPPFLAGS for NO_STABS_SUPPORT
Fix building minidump processor for MinGW

This is a sub-set of changes in https://breakpad.appspot.com/548002/ with a bit
of updating

- Link minidump_stackwalk, minidump_dump with PTHREAD_LIBS as pthread_cancel is used
- Link minidump_stackwalk with ws2_32 as ntoh functions are used
- Fix wtypes.h include for case sensitive filesystems
- _s function variants should only be used if _MSC_VER, use _r variants with
MinGW (and define _POSIX to ensure they are prototyped)
- Don't try to include arpa/inet.h on Windows
- Don't try to build upload tools, dump_syms_dwarf for MinGW
Build PECOFF/DWARF dump_syms for MinGW

- Substitute MapViewOfFile() for mmap()
- Link dump_syms_dwarf with ws2_32 as ntoh functions are used
Fix building client library and upload tools for MinGW

This is the rest of https://breakpad.appspot.com/548002/, brought up to date

Mainly fix include filenames to be lowercased for case-sensitive filesystems

Removed usage of stdext::checked_array_iterator, which is a MSVC-only feature.

v2:
Refine MinGW changes in HTTPUpload::GetFileContents so it closes file after use

v3:
For consistency, write conditionals in terms of _MSC_VER, not __MINGW32__
Fix common.gypi to allow gyp to generate Makefiles on Windows

The MSVS_VERSION variable does not exist unless we are using the MSVS generator
Teach gyp generated Makefile to build crash_generation_app correctly

- Use linker flag for Windows subsystem
- Use linker flag for unicode
- Add rule for compiling windows resources, using $RC to name the resource compiler
- Rename crash_generation_app.rc to avoid a clash in corresponding .o names

Also
- Fix linking of unit test when built using gyp generated Makefile by providing
needed library

XXX: We need to arrange for the gyp Makefile generator to set
CXXFLAGS="-DUNICODE -D_UNICODE" somewhere when generating for Windows.  This is
already done in generated MSVS projects.
Default debug_file to the code_file basename

Strip any path from code_file, and use that as debug_file if one isn't recorded
in the codeview record.

The current implementation of 'ld --build-id' doesn't write a pdbfilename in the
codeview record, not least because we don't have such a thing.

The minidump processor requires both debug_file and debug_identifier (the
build-id) to locate the symbol file.
Fix building windows client unit-tests with gcc

- MinGW doesn't have  _CrtSetReportMode

- Trying to call PureVirtual() on a base class object give a linker error

(Presumably gcc can see that base class will be used for virtual function call,
so requires  an implementation (which is prohibited because it's pure virtual)
at link time.)

XXX: crash_generatation_app manages to contain a pure virtual call without
tripping over this, so look how it does that...
DIA is a problem

symsrv_convert and dump_syms cannot be built with MinGW, because they require
the MS DIA (Debug Interface Access) SDK.

Note that the DIA SDK is not in the Express editions of Visual Studio.

The DIA SDK also uses ATL.

See https://groups.google.com/forum/#!topic/google-breakpad-discuss/F0jMWxmWk0M
for a change to remove that dependency. Code now at
https://github.com/luser/dump_syms
Add symsrv_convert

- Add symsrv_convert from  http://hg.mozilla.org/users/tmielczarek_mozilla.com/fetch-win32-symbols/
- Add building symsrv_convert to .gyp file
- Fix compilation with MSVS 2013
- Disable warning 4702, needed to build omap.cc without getting unreachable code
warning in xtree internal header.
- NOMINMAX should not be needed as that comes from target_defaults
Build MinGW client library and some tools using gyp-generated Makefile

Make what it's possible to make with gyp for MinGW.  Tools which rely on DIA
(dump_syms, ms_symbol_server_converter) cannot be built for MinGW.
Use a default debug-id of all zeros when no CV record is present

This lets us do something slightly useful with current binaries
which are produced without a CV record, but there is no guarantee
that the actually match.
Increase RA scanning to 60 words

http://code.google.com/p/google-breakpad/issues/detail?id=452
Use __USE_MINGW_ANSI_STDIO for MinGW build

Use __USE_MINGW_ANSI_STDIO for ANSI C99 compatible implementation of printf()
and friends on MinGW
Provide a working strtok_r for MinGW

Emulating it using strtok will not work as re-entrancy is required
Add a README.md with notes on what is left to do
