Subject: [PATCH 1/5] parser: rename VERSION token to IPHDRVERSION
A token name of VERSION results in a macro being defined
with the same name. This prevents inclusion of config.h
in commonly used headers.

Subject: [PATCH 2/5] datatype: use mpz_set_str instead of gmp_sscanf
This simplifies the integer parsing logic and restricts it to
functions being part of the mini-gmp subset.

Subject: [PATCH 3/5] erec: use stdio vasprintf instead of gmp_vasprintf
Use stdio's vasprintf instead of gmp_vasprintf which is not part
of the mini-gmp function subset. Furthermore convert the only
gmp-specific user and allow the compiler to verify format-strings.

Subject: [PATCH 5/5] build: add --without-libgmp switch to disable use of
shared libgmp
This disables linking the >400 KB big libgmp and replace it with
the builtin mini-gmp which only increases size by ~30KB.
