Several people have requested that the assert macros in EUnit should be
moved out to a separate header file. This patch puts them in
stdlib/include/assert.hrl, which gets included by the eunit.hrl file.
Thus, nothing changes for eunit users, but the asserts can now also be
included separately.

This reverts commit e56cf8d9846e51ae88fa72c8b0992d81da6fd7d5.

Applications that use the new erl_anno module are depending on STDLIB 2.5.

Note that CosNotification, Megaco, SNMP, Xmerl, and Parsetools use the
erl_anno module via the Yecc parsers only (the header file in
lib/parsetools/include/yeccpre.hrl calls the erl_anno module).

HiPE does not call the erl_anno module, but uses an exported type.
We have chosen to make HiPE dependent on the erl_anno module.

A convenience macro used for testing message passing logic by allowing
to fail if a message matching a `Guard` is not received in the mailbox
of the current process.

This reverts commit e09dd66dc4d89c62ddfd8c19791f9678d5d787c6.
