When configure detects some NO_XXX or NEEDS_XXX is unneeded, unset
this variable (actually set it to empty string). This allow
autodetection to override the default set in Makefile.
[jc: while at it fixed a thinko in IPv6 detection.]

NEEDS_SSL_WITH_CRYPTO means you cannot just say "-lcrypto" to
use SHA1 stuff, but need to say "-lcrypto -lssl".

Add custom test for checking whether formatted IO functions
(printf/scanf et.al.) support 'size specifiers' introduced by C99,
namely ll, hh, j, z, t. (representing long long int, char, intmax_t,
size_t, ptrdiff_t).

This patch adds support for setting either PYTHON_PATH or NO_PYTHON to
autoconf generated ./configure script via --with-python=PATH (sets
PYTHON_PATH) or --without-python (sets NO_PYTHON). Autodetect
PYTHON_PATH via AC_PATH_PROGS.

Move site configuration section, i.e. --with-PACKAGE[=ARG] and

options to the beginning of configure.ac file, just after definitions
of macros.

Not quoting macro arguments that contain other macros is a big no-no in
Autoconf. It can break at any time.

./configure script checks now for the following programs:
* CC - using AC_PROG_CC
* AR - using AC_CHECK_TOOL among ar
* TAR - among gtar, tar
Checks not implemented:
* INSTALL - needs install-sh or install.sh in sources
* RPMBUILD - not known alternatives for rpmbuild
* PYTHON - no PYTHON variable in Makefile,
has to set NO_PYTHON if not present

./configure script checks now if the following libraries are present:
* -lssl for SHA1_Init (NO_OPENSSL)
* -lcurl for curl_easy_setopt (NO_CURL)
* -lexpat for XML_ParserCreate (NO_EXPAT)
It also checks if adding the following libraries are needed:
* -lcrypto for SHA1_Init (NEEDS_SSL_WITH_CRYPTO)
* -liconv for iconv (NEEDS_LIBICONV)
* -lsocket for socket (NEEDS_SOCKET)
Policy: we check also if NEEDS_LIBRARY libraries are present, even if
there is no NO_LIBRARY variable.

./configure script checks now for the following library functions:
* strcasestr (NO_STRCASESTR)
* strlcpy (NO_STRLCPY)
* setenv (NO_SETENV)
in default C library and in libraries which have AC_CHECK_LIB done for
them.
Checks not implemented:
* NO_MMAP - probably only via optional features configuration
* NO_IPV6 - what does "lack IPv6 support" mean?
* NO_ICONV - what does "properly support iconv" mean?

Prepares configure.ac to output autodetected and selected (by using
--with/--without and --enable/disable parameters to generated
./configure script) building configuration in "git style", i.e. by
appending appropriate variables to output file config.mak.autogen
(via temporary file config.mak.append).

This is beginning of patch series introducing installation configuration
using autoconf (and no other autotools) to git. The idea is to generate
config.mak.autogen using ./configure (generated from configure.ac by running
autoconf) from config.mak.in, so one can use autoconf as an _alternative_ to
ordinary Makefile, and creating one's own config.mak. Local settings in
config.mak override generated settings in config.mak.autogen
This patch includes minimal configure.ac and config.mak.in, so one can set
installation directories using autoconf generated ./configure script
e.g. ./configure --prefix=/usr
