dev-libs/json-parser: new package, add 1.1.0_p20211208

Original version 1.1.0 is from a year 2014, which is quite old. The
snapshot is from latest commit 531a49062975 ("Add author of #154 to
AUTHORS") in master branch, which contains (among others) two fixes
related to strict aliasing. New release is anticipated [1], but it is
not clear when it will happen, as the ticket is open for 2 years
already.

It was necessary to apply one patch proposed as PR [2] to upstream,
which changes pkgconfig file installation path from datadir to libdir.

This library is currently known to be bundled in multiple packages in
::gentoo, see the corresponding bugs bellow.
