Newer versions of glibc no longer export the getpagesize() prototype when
using recent versions of POSIX (_XOPEN_SOURCE). So building tdb.c gives
use implicit function declaration warnings. Fix the issue by using the
portable sysconf() function which returns the same answer.

Optimize how the tdb library so that running with [scratch_files] in
/etc/e2fsck.conf is more efficient. Use a better hash function,
supplied by Rogier Wolff, and supply an estimate of the size of the
hash table to tdb_open instead of using the default (which is way too
small in most cases). Also, disable the tdb locking and fsync calls,
since it's not necessary for our use in this case (which is
essentially as cheap swap space; the tdb files do not contain
persistent data.)

Turns out the Hurd defines MS_SYNC but doesn't define msync(). Go
figure. So check for both.

The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

Solaris's header files are very picky about which C compiler can be
used for SUSv3 conformance. Use of C99 is not compatible with SUSv2
(_XOPEN_SOURCE=500), and C89 is not compatible with SUSv3
(_XOPEN_SOURCE=600). Since we need some SUSv3 functions, consistently
use SUSv3 so that e2fsprogs will build on Solaris using c99.

DJGPP lacks sys/select.h and sys/un.h; add header checks to be more
portable.
