MIPS has a different errno for "directory not empty".

Fix PSI idle and socket instrumentation in threadpool

OpenSSL problems, part II

when they're not needed anymore. Helps when
daemonizing it from mysql.init

(Fixing both InnoDB and XtraDB)

Re-opening a TABLE object (after e.g. FLUSH TABLES or open table cache
eviction) causes ha_innobase to call
dict_stats_update(DICT_STATS_FETCH_ONLY_IF_NOT_IN_MEMORY).

Inside this call, the following is done:
  dict_stats_empty_table(table);
  dict_stats_copy(table, t);

On the other hand, commands like UPDATE make this call to get the "rows in
table" statistics in table->stats.records:

  ha_innobase->info(HA_STATUS_VARIABLE|HA_STATUS_NO_LOCK)

note the HA_STATUS_NO_LOCK parameter. It means, no locks are taken by
::info() If the ::info() call happens between dict_stats_empty_table
and dict_stats_copy calls, the UPDATE's optimizer will get an estimate
of table->stats.records=1, which causes it to pick a full table scan,
which in turn will take a lot of row locks and cause other bad
consequences.

Also add fallback version string for unknown future versions.

Ensure atomic appends to the error log by using CreateFile with
FILE_APPEND_DATA flag to open error log file (both MTR and server)

fix PLUGIN_VAR_NOSYSVAR | PLUGIN_VAR_NOCMDOPT plugin thdvars to work.
use that for server_audit_loc_info

my_offsetof() returns a difference of two pointers, it must use the
appropriate return type (my_ptrdiff_t, not size_t)

when opening a system table for a SELECT-like read, pretend
(for the sake of engines) it's SQLCOM_SELECT

There was race condition between online ALTER TABLE and statements performing
TABLE_SHARE release without marking it flushed (e.g. in case of table cache
overflow, SET @@global.table_open_cache, manager thread purging table cache).

The reason was missing mysql_cond_broadcast().

Linking tokudb with jemalloc privately causes problems on library
load/unload. To prevent dangling destructor pointers, link with the same
library as the server is using.

mincore is defined differently in BSD mincore(void *, size_t, char *) vs
linux variant of: mincore(void *, size_t, unsigned char *).
Account for this difference in TokuDB.

it was supposed to be used in command-line tools only.
Different fix for 4e547386:

Bug#24388746: PRIVILEGE ESCALATION AND RACE CONDITION USING CREATE TABLE

different fix for a63a250d:

BUG#23509275 :DBUG_PRINT in THD::decide_logging_format prints incorrectly, access out-of-bound

different fix for 07a33cdc:

Bug #23296299 : HANDLE_FATAL_SIGNAL (SIG=11) IN MY_TOSORT_UTF32

ENOTEMPTY is 247 on hppa, not 39 like on Linux, according to this report:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=837369

So add another replacement for this to rpl.rpl_drop_db and
binlog.binlog_databasae tests (there were already a couple similar
replacements for other platforms).

The motivation for this is that Perl is moving towards not having
current directory ./ in @INC by default. This is causing
mysql-test-run.pl to fail in latest Debian Unstable:

  https://lists.debian.org/debian-devel-announce/2016/08/msg00013.html

However, we have `use "lib"`, there is no need for current directory
in @INC, except for a gross hack. In mtr_cases.pm, there is a
`require "mtr_misc.pl"`, which hides mtr_misc.pl away in mtr_cases
namespace. And things only work because mysql-test-run.pl loads it
with a different name, `require "lib/mtr_misc.pl"`! (Perl will
`require` only once for each unique filename).

Fix this by only using `require` in main program, and referencing
functions with :: scope from other namespaces. For multi-use in
different namespaces, proper `use` modules should be used.
