dev-libs/libstrophe: add new package

A dependency of net-im/profanity.

Based on chaoslab-overlay.
Thanks Ian Moone for high quality work!

Changes made to original work are motivated by avoidance of
overcomplication, and conformance to current practices.

Changes are:
* USE flag 'xml' changed to existing global flag 'expat'
* USE flag 'doc' now also installs examples
* README file is not installed anymore, as it contains mostly
  compilation advise, which is useless once you have it installed
* USE flags 'static-libs', 'ssl' are dropped
* RESTRICT="mirror" dropped as unreasonable.
