bitbake: hashserv: Add support for equivalent hash reporting

The reason for this should be recorded in the commit logs. Imagine
you have a target recipe (e.g. meta-extsdk-toolchain) which depends on
gdb-cross. sstate in OE-Core allows gdb-cross to have the same hash
regardless of whether its built on x86 or arm. The outhash will be
different.

We need hashequiv to be able to adapt to the prescence of sstate artefacts
for meta-extsdk-toolchain and allow the hashes to re-intersect, rather than
trying to force a rebuild of meta-extsdk-toolchain. By this point in the build,
it would have already been installed from sstate so the build needs to adapt.

Equivalent hashes should be reported to the server as a taskhash that
needs to map to an specific unihash. This patch adds API to the hashserv
client/server to allow this.
