* acinclude.m4, configure.in: Put all libraries into their
own *_LIB variables instead of $LIB so that we do not have to
link in the world to all executables. Modified SANE_CHECK_U_TYPES
to be a little more portable to platforms that use #define
for u_* types. Create SANE_CHECK_BACKENDS macro so that
PRELOADABLE_BACKENDS can also be valided. Auto-populated
PRELAODABLE_BACKENDS when detect dlopen() won't work.
Various protability cleanups.
* backend/dll.c: Make dll-preload.c a .h since its an include and
not compilable byitself.
* frontend/Makefile.in, frontend/scanimage.c, include/laaloca.h,
lib/Makefile.am, lib/alloca.c, strcasestr.c, tools/Makefile.in,
tools/sane-desc.c: Convert lib/ to automake. Create a liblib.la
for everyone to use and a libfelib.la for only frontend programs.
Make all internal programs be prefixed with sanei_ as not to conflict
with other programs libsane is linked in with that will also most
likely create similar internal utils on problem platforms.
* include/getopt.h, lib/getopt.c, lib/getopt1.c: Always compile
and link in getopt_long() but prefix it with sanei_. Its
easier to always use internal version then try to figure out what
platforms support getopt_long() and what header files to use.
* backend/Makefile.am: Convert backend makefile to automake.
Initial version that is feature parity with original but uses
specific rules instead of wildcards and only links in libraries/objs
really required. Room for more cleanup of whats linked in once
all makefiles have been converted to automake.
