[RFC/PATCH 7] autoconf: Checks for libraries
./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.

Needs checking if correct functions are used for checks.
Policy might need to be changed, too.
