I was able to get the alpine package maintainers
to merge in a patch for tcsh that fixed the out
of memory issues when attempting to use it as seen
here: https://github.com/alpinelinux/aports/pull/3302.
This commit has been lightly hand tested and basic
tcsh features appear to work. There are some failures
on alpine with the tcsh regression test suite which
can be seen here: http://tpaste.us/L6R4.

Associated symlinks that replaced tcsh with bash have
been removed as a result of this update.

Squashed commit of the following:
