./configure script checks now for existence of the following types and structure members: * dirent.d_ino in dirent.h (NO_D_INO_IN_DIRENT) * dirent.d_type in dirent.h (NO_D_TYPE_IN_DIRENT) * 'struct sockaddr_storage' in netinet/in.h (NO_SOCKADDR_STORAGE)
./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 (crypto, curl, expat).
NOTE: not all checks are implemented!

This patch needs review by someone better versed in compiling git on different platforms, namely AC_CHECK_MEMBER and AC_CHECK_TYPE needs checking if all header files where git search for specified structure member or specified type.
I don't know (yet) how to implement checking for NEEDS_SSL_WITH_CRYPTO (probably also checlking for crypto library needs correction), NEEDS_LIBICONV, NEEDS_SOCKET, NO_IPV6, NO_ICONV, Python < 2.3 and Python == 2.3, if to check for NO_MMAP, and for NO_ACCURATE_DIFF.
This patch is to be considered preliminary!
