(raptor_log_error): sizeof should take size of field not pointer
Allow xml2-config and curl-config to work for libxml and libcurl

- report on source of xml, curl libraries in status
- remove extra oCPPFLAGS assignements
- substitute pkgconfig dependencies into raptor2.pc
fix PKG_CONFIG_REQUIRES version vars
Delete win32/ subdirectory

The MSVC6 and MSVC7.1 project files in win32/ fail to build current
versions of Raptor, require external projects for Curl and Expat which do
not appear to be publicly available, are unlikely to get the extensive work
they need in the near future due to John Barstow's busy schedule, and are
redundant now that Raptor can be built on Windows using CMake. Thus, out
they go.

win32/README.md: Moved up to README-cmake.md, as this information is
useful, and CMake build support is not limited to Win32
Remove all traces of win32_raptor_config.h

Remove the file itself, all #include uses of it, and all references to it,
as this file is no longer needed.
Simplify CMake usage with CMAKE_INCLUDE_CURRENT_DIR
Update Autoconf syntax per autoupdate(1)

autogen.sh: Added -Wall to aclocal and autoconf invocations, which was what
uncovered the need to run autoupdate in the first place

configure.ac: Modified by autoupdate, cleaned up by hand afterward

#changes
Ensure that a small system BUFSIZ does not affect parser guessing

raptor_internal.h: Ensure that RAPTOR_READ_BUFFER_SIZE is never smaller than 4096. (It really only needs to be as large as FIRSTN in raptor_parse.c, i.e. 1024, but 4kB isn't all that much nowadays anyway)

(raptor_world_guess_parser_name): Added a compile-time check to ensure that RAPTOR_READ_BUFFER_SIZE is at least as large as FIRSTN, because otherwise the guesser sees fewer than FIRSTN bytes from the document.
Fix DLL export linkage for internal functions needed by the test programs

This allows the test programs to be linked against a DLL build of Raptor.
