gattlib: add recipe

gattlib is a C library for talking to Bluetooth, including BLE,
devices. It's the only free, embedded-appropriate library for
easily scanning BLE devices and subscribing to their notifications

+Subject: [PATCH] dbus: avoid 'strange' chars from the build dir in #defines
+
+gdbus-codegen uses include guards with the full path dir, and if there
+are "bad" characters, such as '+', this fails miserably. E.g. Yocto has a
+tendency to build in directories named from the Yocto package version and
+that package version containing a '+' are not uncommon, and even the
+standard in certain scenarios such as when using ${SRCPV}.
+
+Avoid the problem of the full path "leaking" into the source by avoiding
+the normal include guards and request "#pragma once" instead.
