Support platforms where mkdir only takes one argument (eg., MS-Windows)

Include limits.h in files which used PATH_MAX for portability

Avoid unportable "uint" type

Add support for platforms without fnmatch.

This uses gnulib so you will need to have a copy in order
to run autogen.sh (but not to build from a tarball). Either
arrange for gnulib-tool to be in your path or set the
environment variable GNULIB_TOOL to point to its location.

Support platforms without mmap

Make curl an optional dependancy

Make rpmlib an optional dependency

Use configure --without-rpm to avoid the dependency (default is unchanged).

Reduce intltool requirements to version 0.35 for compatibility with Centos 5

Use strings to identify section types in the on-disk repo format.

Previously, a given razor file type had a fixed number of sections in a
fixed order, identified by an integer type. Now, sections are identified
by a named string (stored in a string pool after the section lists).

This will allow for razor files to contain arbitrary sections.

For bonus points, also drop the 4k section alignment and change the
magic byte string to "RZDB".

Convert main.c to use razor_root for most cases.

With this we change the default repo location to /var/lib/razor, but let the env
variable RAZOR_ROOT override it.
