The tests for POSIX threads can now be controlled by the user with the
--enable-pthreads=FLAGS option.  If this is set (to some value other
than yes or no), the value is passed to the compiler.  Thread support
is based solely on the outcome of this test.  The user may specify not
to use threading at all or to use the default tests (first -pthread
then -lpthread) by not specifying FLAGS when passing --enable-pthreads.

Libraries that can have user specificed base paths are wrapped with
GIT_STASH_FLAGS/GIT_UNSTASH_FLAGS to ensure that the proper versions
on the system are tested.  This ensures, for example, that the zlib
tests for deflateUnbound are done with the version of zlib requested
by the user.  This is most useful in the absence of good settings for
CPPFLAGS and/or LDFLAGS.

Move the argument tests from the 'site overrides' so that they are
ahead of any library tests.  This allows for library tests to take
user specified paths into account.  The intent here is to avoid things
like NO_DEFLATE_BOUND being set due to finding old zlib when the user
has specified an alternate location for zlib.  (Ignore the fact that
properly set *FLAGS can avoid solve this issue.)

Update configure.ac to test libraries for getaddrinfo, strcasestr, memmem,
strlcpy, strtoumax, setenv, unsetenv, and mkdtemp.  The default compilers
on FreeBSD 4.9-SECURITY and FreeBSD 6.2-RELEASE-p4 do not generate warnings
for missing prototypes unless `-Wall' is used. This behavior renders the
results of AC_CHECK_FUNC() void on these platforms. The test AC_SEARCH_LIBS()
verifies a function is valid by linking to symbol within the system libraries.

Since this pattern needs to be repeated for many functions that are
checked with AC_CHECK_FUNC(), we add GIT_CHECK_FUNC() to drive the two
autoconf macros together.

On a Solaris machine I have access to libc contains the symbol
"iconv" but, when compiling with gcc and including iconv.h we get
iconv.h from GNU libiconv. This header file define (among other
things) "iconv" to "libiconv" and so on.

In order to link with GNU libiconv we need -liconv. Currently we
test if the symbol "iconv" is in libc (which is true), then we get
a undefined reference error because we don't have libiconv_open.

The solution this patch implements is to compile and link a
small test program, instead of just checking if the libraries
(libc and libiconv) contains the symbol "iconv".
