This helps to catch upgrade problems and simplifies some parts of the code.
Bumped XBPS_RELVER because xbps_remove_pkg() has been changed.

doxygen and graphviz are required. It's disabled by default, use
the BUILD_API_DOCS make(1) argument to enable it.

Also always build the static bins so that it's done in one pass,
that means that objects are PIC and built with SSP.

libfetch from NetBSD's pkgsrc has been imported into lib/fetch, but
the objects are embedded into libxbps. Only a public function to fetch
files has been implemented: xbps_fetch_file().
The library now is built with -fvisibility=hidden by default, and
exported symbols are the ones that use the SYMEXPORT macro.
The code works well enough, but will need many more cleanups.

uses an array of strings that lists the packages that should be
removed before new package can be installed.
In the build templates one can use: replaces="foo foo-blah foo-libs".

* Added XBPS_FETCH_CMD to xbps-src.conf, this will be used to fetch
distfiles. Please note that it will be copied to the chroot, so
it should be statically linked or with only libc required.
* Removed libtool_func.sh and associated vars, it's unneeded currently.
* Added keep_empty_dirs, keep_libtool_archives and nostrip. By default
all empty dirs and libtool archives are removed, and executables and
libraries stripped, respectively. One can use set the var in a build
template to change the behaviour.
* Explain in README what are the requirements to build XBPS.

as foo.static.
Updated README to note the new requirements for it. It will be used
to reduce the number of dependencies when building packages in
the chroot.
