Alex Crichton 7d8d06f86b Remove deprecated functionality
This removes a large array of deprecated functionality, regardless of how
recently it was deprecated. The purpose of this commit is to clean out the
standard libraries and compiler for the upcoming alpha release.

Some notable compiler changes were to enable warnings for all now-deprecated
command line arguments (previously the deprecated versions were silently
accepted) as well as removing deriving(Zero) entirely (the trait was removed).

The distribution no longer contains the libtime or libregex_macros crates. Both
of these have been deprecated for some time and are available externally.
