* Make several fixes regarding typos and licensing (see below)
Since GLFS contains a significant amount of code from BLFS, for legal
reasons the BLFS MIT license must be in the repo. Instead of relicensing
which is a grey area, this commit sublicenses GLFS, as a downstream of
BLFS which it is. Along with this the changelog was added back as this is
a core part of *LFS maintainers
* Add changelog to welcome.xml
* Add a symlink and fix some typos
Update to dhcp-4.3.4.
Update to mercurial-3.7.3.
Update to mesa-11.2.0.
Add BOOK/changelog.xml as a convenience symlink.
