In tcpcheck_eval_connect(), if we're targetting a server, increase its
curr_used_conns when creating a new connection, as the counter will be
decreased later when the connection is destroyed and conn_free() is called.
Getting rid of this warning is cleaner solved using a 'fall through' comment,
because it clarifies intent to a human reader.
This patch adjust a few places that cause -Wimplicit-fallthrough to trigger:
- Fix typos in the comment.
- Remove redundant 'no break' that trips up gcc from comment.
- Move the comment out of the block when the 'case' is completely surrounded
by braces.
- Add comments where I could determine that the fall through was intentional.

This patch fixes all the leftovers from the include cleanup campaign. There
were not that many (~400 entries in ~150 files) but it was definitely worth
doing it as it revealed a few duplicates.
Most of the files dealing with error reports have to include log.h in order
to access ha_alert(), ha_warning() etc. But while these functions don't
depend on anything, log.h depends on a lot of stuff because it deals with
log-formats and samples. As a result it's impossible not to embark long
dependencies when using ha_warning() or qfprintf().
This patch moves these low-level functions to errors.h, which already
defines the error codes used at the same places. About half of the users
of log.h could be adjusted, sometimes revealing other issues such as
missing tools.h. Interestingly the total preprocessed size shrunk by
4%.
Checks.c remains one of the largest file of the project and it contains
too many things. The tcpchecks code represents half of this file, and
both parts are relatively isolated, so let's move it away into its own
file. We now have tcpcheck.c, tcpcheck{,-t}.h.
Doing so required to export quite a number of functions because check.c
has almost everything made static, which really doesn't help to split!
