VTest can now enable mworker and mcli with separate flags so lets
update vtc files that need it. This also allows to revert the change
made with 1545a59c ("REGTESTS: make seamless-reload depend on 1.9
and above").
Since latest updates, vtest requires the master CLI when running in
master-worker mode, and this one is only available starting with 1.9.
The seamless reload test is the only one depending on this and now
fails on 1.8, so let's adjust it accordingly.
This patch replaces LEVEL variable by REGTESTS_TYPES variable which is more
mnemonic and human readable. It is uses as a filter to run the reg tests scripts
where a commented #REGTEST_TYPE may be defined to designate their types.
Running the following command:
$ REGTESTS_TYPES=slow,default
will start all the reg tests where REGTEST_TYPE is defines as 'slow' or 'default'.
Note that 'default' is also the default value of REGTEST_TYPE when not specified
dedicated to run all the current h*.vtc files. When REGTESTS_TYPES is not specified
there is no filter at all. All the tests are run.
This patches also defines REGTEST_TYPE with 'slow' value for all the s*.vtc files,
'bug' value for al the b*.vtc files, 'broken' value for all the k*.vtc files.
Add LEVEL #4 regression testing files which is dedicated to
VTC files in relation with bugs they help to reproduce.
At the date of this commit, all VTC files are LEVEL 4 VTC files.
