GNU Parallel 20150109alpha released

[Ole Tange]

GNU Parallel 20150109alpha has been released. It is available for
download at: http://alpha.gnu.org/gnu/parallel/

To make remote execution send stderr to stderr a major change has been
implemented in remote execution. If you use GNU Parallel for remote
execution (--sshlogin) then please test this alpha release.

As always it passes the testsuite, so most functionality clearly works.

New in this release:

* Remote jobs now sends stderr (standard error) to stderr (standard
error) instead of stdout (standard output).

* Remote execution is now packed using hex encoded bzip2. That means
that big environments (app. 250 KB) can be transferred. This change
makes remote execution alpha quality.

* Bash's second fix of shellshock cause --env to break again when
exporting functions. This has been fixed again.

* --semaphoretimeout now takes a negative value. This means give up if
the semaphore is not gotten within the timeout.

* --halt -1 and -2 now means halt if a job succeeds (so the opposite
of 1 and 2).

* A semibig refactoring of big functions. All non-trivial functions
are now less than 100 lines. The refactoring makes this release beta
quality.
