When a CTE referring to another CTE from the same with clause
was used twice then the server could not find the second CTE and
reported a bogus error message.
This happened because for any unit that was created as a clone of
a CTE specification the pointer to the WITH clause that owned this CTE
was not set.

Mroonga generated far too many warnings (and hence output) for Travis's
sensibilities on output log file size. So we just remove the storage
engine.

Additionally use clang as a compiler, versions 3.8, 3.9 and 4.0

Additionally use gcc/g++-7

Add additional packages used by build now that they are whitelisted.

ha_innobase::defragment_table(): Skip corrupted indexes and
FULLTEXT INDEX. In InnoDB, FULLTEXT INDEX is implemented with
auxiliary tables. We will not defragment them on OPTIMIZE TABLE.

An attempt to mark reference as dependent lead to transfering this property to
original view field and through it to other references of this field which
can't be dependent.

buf_dblwr_create(): Remove a bogus check for the buffer pool size.
Theoretically, there is no problem if the doublewrite buffer is
larger than the buffer pool. It could only cause trouble on crash
recovery, and on recovery the doublewrite buffer is read to a buffer
that is allocated outside of the buffer pool. Moreover, this check
was only performed when the database was initialized for the first
time.

On a normal startup, buf_dblwr_init() would not enforce any
rule on the innodb_buffer_pool_size.

Furthermore, in case of an error, commit the mini-transaction in order
to avoid an assertion failure on shutdown. Yes, this will leave the
doublewrite buffer in a corrupted stage, but the doublewrite buffer
should only be initialized when the data files are being initialized
from the scratch in the first place.

Also, revert part of MDEV-7685 that added an InnoDB abort when
ALTER TABLE…ALGORITHM=INPLACE is reporting that it ran out of
file space.

buf_load(): When the file cannot be opened for reading, issue a note,
not an error message.

fil_crypt_rotate_page - space_id should be compared to TRX_SYS_SPACE not space

debug build with older cmake.

The constant is implicitely defined by VS when chosen C runtime is Debug
(/MTd, MDd).

CMake does not define it since https://public.kitware.com/Bug/view.php?id=15777
was fixed.

We remove it from compile flags, to be able to build Debug with /MT runtime
using older cmakes.

Also  do not use BUILD_BYPRODUCTS in ExternalPeoject for older cmake

The patch actually fixes the old defect of the optimizer that
could not extract keys for range access from IN predicates
with row arguments.

This problem was resolved in the mysql-5.7 code. The patch
supersedes what was done there:
 - it can build range access when not all components of
 the first row argument are refer to the columns of the table
 for which the range access is constructed.
 - it can use equality predicates to build range access
 to the table that is not referred to in this argument.

Also, some MDEV-11738/MDEV-11581 post-push fixes.

In MariaDB 10.1, there is no fil_space_t::is_being_truncated field,
and the predicates fil_space_t::stop_new_ops and fil_space_t::is_stopping()
are interchangeable. I requested the fil_space_t::is_stopping() to be added
in the review, but some added checks for fil_space_t::stop_new_ops were
not replaced with calls to fil_space_t::is_stopping().

buf_page_decrypt_after_read(): In this low-level I/O operation, we must
look up the tablespace if it exists, even though future I/O operations
have been blocked on it due to a pending DDL operation, such as DROP TABLE
or TRUNCATE TABLE or other table-rebuilding operations (ALTER, OPTIMIZE).
Pass a parameter to fil_space_acquire_low() telling that we are performing
a low-level I/O operation and the fil_space_t::is_stopping() status should
be ignored.

To export symbols from the mysqld.exe, use lib.exe with /DEF, rather than
pre-link step when building mysqld.exe.

This helps to avoid relinking all plugins, if mysqld.exe was recompiled
but the list of its exports has not changed.

Also removed unnecessary DEPENDS in some ADD_CUSTOM_COMMAND (gen_lex_token,
gen_lex_hash etc). They confuse VS generator which tends to
recreate headers and do unnecessary recompilations.

We do not use it now, but there is still no reason to break compilation
for other users.
