* configure.ac (SEPCONSTANTS): New to define DIRSEP_C et al.

Browse Source 
* w32-util.c (read_w32_registry_string): Updated from code used by
GnuPG.  This allows for expanding strings and features the
implicit fallback key.
(w32_shgetfolderpath, find_program_at_standard_place): New.
(_gpgme_get_gpg_path, _gpgme_get_gpgsm_path): With no registry
entry, locate the programs at the standard place.
(dlopen, dlsym, dlclose): New, so that we can keep on using what
we are accustomed to.

* debug.c (debug_init): Use PATHSEP_C so that under W32 a
semicolon is used which allows us to create files with drive
letters.

* w32-io.c (_gpgme_io_read, _gpgme_io_write): Print content in
debug mode too.

* "./autogen.sh --build-w32" does now build gpgme.dll.
* [W32] The environment variable GPGME_DEBUG now uses a semicolon as
delimiter. The standard install directory is used when locating
gpg or gpgsm before finally falling back to the hardwired name.
* You can now configure the backend engine file name and home
directory to be used, as default and per context.
