This reverts commit 13884cf2.

Fixed in 5.6 (merged in the next commit)

"x86_64" is "amd64" on FreeBSD

mysql.cc:
Unlike the main MYSQL structure, kill_mysql did not have MYSQL_OPT_PROTOCOL set.

Move all connection-related settings to a separate function and
use it both for the main MYSQL and for kill_mysql.

MDEV-9390 Function found_rows() gives incorrect result where the previous SELECT contains ORDER BY clause

use the raw found_rows value only when SQL_CALC_FOUND_ROWS was specified

following InnoDB's logic, altering a comment or a default
field's value needs "NO_LOCK", not EXCLUSIVE

Only set Alter_inplace_info::ALTER_COLUMN_VCOL flag if
a vcol might be affected by the ALTER TABLE statement

Followup fix for bug#35074: update the second location where
max_used_connections is calculated (to be like the
first one).

fix a few cases where a successful ALTER was not binlogged:
* on errors after the completed ALTER, binlog it, then return an error
* don't let thd->killed abort open_table() after completed
  online ALTER.

Fix the doubly questional fix for MySQL Bug#17250787:
* it detected autoinc index by looking for the first index
  that starts from autoinc column. never mind one column
  can be part of many indexes.
* it used autoinc_field->field_index to look up into internal
  innodb dictionary. But field_index accounts for virtual
  columns too, while innodb dictionary ignores them.

Find the index by its name, like elsewhere in ha_innobase.

don't use ipv6 is the check fails for any reason. for example, an
ancient solaris perl didn't have sockaddr_in6() in Socket at all.

it caused feedback plugin tests to fail

1. ignore generated dtrace files
2. don't rewrite probes_mysql_nodtrace.h in-place

1. check that unused inline functions are removed
2. only allow compilation if they are or if the check if overridden
3. with CMAKE_GENERATOR=Makefiles, use all flags when testing
   (e.g. both CMAKE_C_FLAGS and CMAKE_C_FLAGS_DEBUG if
   CMAKE_BUILD_TYPE=Debug). This is because
 - on Solaris with the SunPro compiler, default CMAKE_C_FLAGS_xxx
   values contain -xO2 (for Release and RelWithDebInfo)
   and -g (for RelWithDebInfo and Debug)
 - proper inlining only works at -xO4 without -g
 - so if CMAKE_C_FLAGS has -xO4, inlining would work in
   configure.cmake (before this fix) and fail during actual compilation

also remove the outdated check for inline from myu_global.h

1. unused static inline functions are only removed at -xO4,
   otherwise test binaries will depend on various mysys
   symbols that they don't use. Link test with libmysys.

2. Sphinx - don't instantiate (explicitly) templates before
   they're defined. Or, rather, don't instantiate them explicitly at
   all.

3. GIS - don't use anonymous unions and structs.

In case of missing includedir file, we would attempt to free a NULL
pointer. Make sure to guard against that.

In the case of error during my_load_defaults, we would not free the
args array.

dml_setup_instruments did not restore settings in setup_instruments table
after updating it as a part of the test flow
