gnu: igraph: Update to 0.10.7.
* gnu/packages/graph.scm (igraph): Update to 0.10.7.
[source]: Use git-fetch. Apply patch.
<snippet>: Remove the entire "vendor" and "src/isomorphism/bliss" directories.
Patch CMakeLists.txt to not build and use vendored dependencies.
[arguments]: Add -DIGRAPH_INTEGER_SIZE=64 to #:configure-flags. Add phases to
use unbundled libraries and build documentation.
[native-inputs]: Add bison, docbook-xml-4.3, docbook-xsl, flex, pcg-c, python,
source-highlight and xmlto.
[inputs]: Remove gmp and libxml2. Add bliss and suitesparse-cxsparse.
* gnu/packages/patches/igraph-fix-varargs-integer-size.patch: New file.
* gnu/local.mk (dist_patch_DATA): Register it.

If the size of int is different from IGRAPH_INTEGER_SIZE, the integer size
passed to these vararg arguments is different from the assumed one,
leading to undefined behavior.
