autotools: use pcre for regular expressions
Added the necessary autotools rules to use pcre in the src binaries
and libsyncevolution. It's unconditionally required now, which makes
it possible to add code depending on it without having to worry about
the case without pcre.
The alternative to pcre with its C++ binding would have been
boost::Xpressive. pcre was chosen because it has UTF-8 support and is
more common.
boost::regex introduces an undesirable library dependency. The C POSIX
regex code has no C++ binding and does not support easy replacement.
README was updated accordingly.
