Marko Mäkelä 4e1116b2c6 MDEV-12271 Port MySQL 8.0 Bug#23150562 REMOVE UNIV_MUST_NOT_INLINE AND UNIV_NONINL
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.
