Problem:
========
During checkpoint, we are writing all MLOG_FILE_NAME records in one mtr
and parse buffer can't be processed till MLOG_MULTI_REC_END. Eventually parse
buffer exceeds the RECV_PARSING_BUF_SIZE and eventually it overflows.
Fix:
===
1) Break the large mtr if it exceeds LOG_CHECKPOINT_FREE_PER_THREAD into multiple mtr during checkpoint.
2) Move the parsing buffer if we are encountering only MLOG_FILE_NAME
records. So that it will never exceed the RECV_PARSING_BUF_SIZE.

Also, remove empty .ic files that were not removed by my MySQL commit.
Problem:
InnoDB used to support a compilation mode that allowed to choose
whether the function definitions in .ic files are to be inlined or not.
This stopped making sense when InnoDB moved to C++ in MySQL 5.6
(and ha_innodb.cc started to #include .ic files), and more so in
MySQL 5.7 when inline methods and functions were introduced
in .h files.
Solution:
Remove all references to UNIV_NONINL and UNIV_MUST_NOT_INLINE from
all files, assuming that the symbols are never defined.
Remove the files fut0fut.cc and ut0byte.cc which only mattered when
UNIV_NONINL was defined.
Define my_thread_id as an unsigned type, to avoid mismatch with
ulonglong. Change some parameters to this type.
Use size_t in a few more places.
Declare many flag constants as unsigned to avoid sign mismatch
when shifting bits or applying the unary ~ operator.
When applying the unary ~ operator to enum constants, explictly
cast the result to an unsigned type, because enum constants can
be treated as signed.
In InnoDB, change the source code line number parameters from
ulint to unsigned type. Also, make some InnoDB functions return
a narrower type (unsigned or uint32_t instead of ulint;
bool instead of ibool).
InnoDB keeps track of buffer-fixed buf_block_t or acquired rw_lock_t
within a mini-transaction. There are some memo_contains assertions
in the code that document when certain blocks or rw_locks must be held.
But, these assertions only check the mini-transaction memo, not the fact
whether the rw_lock_t are actually being held by the caller.
btr_pcur_store_position(): Remove #ifdef, and assert that the block
is always buffer-fixed.

WL#7682 in MySQL 5.7 introduced the possibility to create light-weight
temporary tables in InnoDB. These are called 'intrinsic temporary tables'
in InnoDB, and in MySQL 5.7, they can be created by the optimizer for
sorting or buffering data in query processing.
In MariaDB 10.2, the optimizer temporary tables cannot be created in
InnoDB, so we should remove the dead code and related data structures.

MDEV-10547: Test multi_update_innodb fails with InnoDB 5.7
The failure happened because 5.7 has changed the signature of
the bool handler::primary_key_is_clustered() const
virtual function ("const" was added). InnoDB was using the old
signature which caused the function not to be used.
