When compiled with "-Wl,-Bsymbolic-functions" flags
(e.g. when building a .deb package on Ubuntu) with TokuDB and jemalloc,
mysqld crashed in toku_get_processor_frequency_cpuinfo() when
free()-ing a buffer returned by getline().
getline() uses libc malloc() internally, while free() is aliased
to jemalloc's free() in this configuration.
Fixing not to use getline(). Using a static buffer instead.
Fix all cmake tests (including plugin) to use
MY_CHECK_AND_SET_COMPILER_FLAG. And fix that function
to be compatible with cmake 3.0. This way flag checks
are correctly cached (even in cmake 3.0) and properly reused.
In original code, sometimes one got an automatic DEFAULT value in some cases, in other cases not.
For example:
create table t1 (a int primary key) - No default
create table t2 (a int, primary key(a)) - DEFAULT 0
create table t1 SELECT .... - Default for all fields, even if they where defined as NOT NULL
ALTER TABLE ... MODIFY could sometimes add an unexpected DEFAULT value.
The patch is quite big because we had some many test cases that used
CREATE ... SELECT or CREATE ... (...PRIMARY KEY(xxx)) which doesn't have an automatic DEFAULT anymore.
Other things:
- Removed warnings from InnoDB when waiting from semaphore (got this when testing things with --big)

be less annoying about sysvar-based table attributes
do not *always* add them to the create table definition,
but only when a sysvar value is different from a default.
also, when adding them - don't quote numbers

Remove ONLY_IF clause in MYSQL_ADD_PLUGIN and the requirement
that every plugin's CMakeLists.txt *must* do MYSQL_ADD_PLUGIN
for PLUGIN_XXX=YES to work. This was very fragile and cannot be
relied on.
Use a different implementation of =YES check - iterate all
PLUGIN_* variables and see which one doesn't have a matching target.
Revert all ONLY_IF changes in CMakeLists.txt files.
