Introduce execution domains in code and building

Only fixed to compile. Untested.

Lots of refactoring, cleanup, and fixing in the process.
This log has three parts:
1. What are execution domains and why we need them
2. What are the API incompatibilities introduced...

Move segment unmap() in xsegbd module.

We cannot unmap a segment in xseg_destroy(), since the segment may not

xsegbd_xseg_quit(), inside the xsegbd module.

Make sure to unmap the segment in xseg_destroy()

Add xops->unmap() in xseg_destroy(). If you don't unmap the segment before

Add support for X_INFO request operation, to query information about a

relax shared segment access precautions

The shared array of peer type names is by design
append only, therefore no locking or copying strings
is needed to access it (only pointer conversions).
Append-only means that peer type names cannot be unregistered....

fix invalid shared pointer access and wrong retval

also, lock and copy string from shared segment,
