* Update mysqld_safe script to remove duplicated parameter --crash-script
* Make --core-file-size accept underscores as well as dashes correctly.
* Add mysqld_safe_helper to Debian and Ubuntu files.
* Update innodb minor version to 35
This patch ports the work that facebook has performed
to make innochecksum handle compressed tables.
the basic idea is to use actual innodb-code to perform
checksum verification rather than duplicating in innochecksum.cc.
to make this work, innodb code has been annotated with
lots of #ifndef UNIV_INNOCHECKSUM so that it can be
compiled outside of storage/innobase.
A new testcase is also added that verifies that innochecksum
works on compressed/non-compressed tables.
Merged from commit fabc79d2ea976c4ff5b79bfe913e6bc03ef69d42
from https://code.google.com/p/google-mysql/
The actual steps to produce this patch are:
take innochecksum from 5.6.14
apply changes in innodb from facebook patches needed to make innochecksum compile
apply changes in innochecksum from facebook patches
add handcrafted testcase

Update InnoDB to 5.6.14
Apply MySQL-5.6 hack for MySQL Bug#16434374
Move Aria-only HA_RTREE_INDEX from my_base.h to maria_def.h (breaks an assert in InnoDB)
Fix InnoDB memory leak
support ha_innodb.so as a dynamic plugin.
* remove obsolete *,innodb_plugin.rdiff files
* s/--plugin-load=/--plugin-load-add=/
* MYSQL_PLUGIN_IMPORT glob_hostname[]
* use my_error instead of push_warning_printf(ER_DEFAULT)
* don't use tdc_size and tc_size in a module
update test cases (XtraDB is 5.6.14, InnoDB is 5.6.10)
* copy new tests over
* disable some tests for (old) InnoDB
* delete XtraDB tests that no longer apply
small compatibility changes:
* s/HTON_EXTENDED_KEYS/HTON_SUPPORTS_EXTENDED_KEYS/
* revert unnecessary InnoDB changes to make it a bit closer to the upstream
fix XtraDB to compile on Windows (both as a static and a dynamic plugin)
disable XtraDB on Windows (deadlocks) and where no atomic ops are available (e.g. CentOS 5)
storage/innobase/handler/ha_innodb.cc:
revert few unnecessary changes to make it a bit closer to the original InnoDB
storage/innobase/include/univ.i:
correct the version to match what it was merged from
InnoDB: Remove HAVE_purify, UNIV_INIT_MEM_TO_ZERO, UNIV_SET_MEM_TO_ZERO.
The compile-time setting HAVE_purify can mask potential bugs.
It is being set in PB2 Valgrind runs. We should simply get rid of it,
and replace it with UNIV_MEM_INVALID() to declare uninitialized memory
as such in Valgrind-instrumented binaries.
os_mem_alloc_large(), ut_malloc_low(): Remove the parameter set_to_zero.
ut_malloc(): Define as a macro that invokes ut_malloc_low().
buf_pool_init(): Never initialize the buffer pool frames. All pages
must be initialized before flushing them to disk.
mem_heap_alloc(): Never initialize the allocated memory block.
os_mem_alloc_nocache(), ut_test_malloc(): Unused function, remove.

Some ut_a(!rec_offs_any_null_extern()) assertion failures are indicating
genuine BLOB bugs, others are bogus failures when rolling back incomplete
transactions at crash recovery. This needs more work, and until I get a
chance to work on it, other testing must not be disrupted by this.
If UNIV_DEBUG or UNIV_BLOB_LIGHT_DEBUG is enabled, add
!rec_offs_any_null_extern() assertions, ensuring that records do not
contain null pointers to externally stored columns in inappropriate
places.
btr_cur_optimistic_update(): Assert !rec_offs_any_null_extern().
Incomplete records must never be updated or deleted. This assertion
will cover also the pessimistic route.
row_build(): Assert !rec_offs_any_null_extern(). Search tuples must
never be built from incomplete index entries.
row_rec_to_index_entry(): Assert !rec_offs_any_null_extern() unless
ROW_COPY_DATA is requested. ROW_COPY_DATA is used for
multi-versioning, and therefore it might be valid to copy the most
recent (uncommitted) version while it contains a null pointer to
off-page columns.
row_vers_build_for_consistent_read(),
row_vers_build_for_semi_consistent_read(): Assert !rec_offs_any_null_extern()
on all versions except the most recent one.
trx_undo_prev_version_build(): Assert !rec_offs_any_null_extern() on
the previous version.
rb:682 approved by Sunny Bains
Replace UNIV_BLOB_NULL_DEBUG with UNIV_DEBUG||UNIV_BLOB_LIGHT_DEBUG.
Fix known bogus failures.
btr_cur_optimistic_update(): If rec_offs_any_null_extern(), assert that
the current transaction is an incomplete transaction that is being
rolled back in crash recovery.
row_build(): If rec_offs_any_null_extern(), assert that the transaction
that last updated the record was recovered during crash recovery
(and will soon be rolled back).
