a "if"
Bug #41913 mysqltest cannot source files from if inside while
Some commands require additional processing which only works first time
Keep content for write_file or append_file with the st_command struct
Add tests for those cases to mysqltest.test

Some follow-up test fixes after seeing effect in PB2

Rewrote logic (first commit was incomplete, sorry)

Apparently caused by logging to table
Turn on logging to file only, add to .opt file for tests needing log to table

Moved some dynstr_free() further up

Enabled proper pattern for Warnings and ERRORs
Added some suppressions

 - Add conditionals for bundled zlib and innodb plugin.
 - Apply patch from bug#46834 to install the test suite in RPMs.
 - Add plugins to RPMs.  Disable example plugins.

This is a partial correction to the original fix for bug#37098
   Get rid of "Installed (but unpackaged)" files in the RPM build
which used a wrong variable.

diff was actually called but result never outputted before exiting
Added extra code to dump output *unless* failure was expected

Moved some dynstr_free() further up

Quicker test collection and better output with --start[-dirty]

Fixed in two comments as well

This involves merge changesets and backports into QSP builds only,
does not cause a contents change in 5.1

Adding @<platform> syntax

not ready to run with innoplug-1.0.4.

Output would match an empty result file but we don't check
Allow empty output IFF there is an empty result file.

automerge didn't handle this correctly,
so test "view" was corrected manually.

The test for the 45806 entry in our bug DB got applied twice,
in different places for the "view.test" and "view.result" files.

The fix is to simply remove the erroneous insertion.
