Marko Mäkelä a87bb96ecb MDEV-36234: Add innodb_linux_aio
This controls which linux implementation to use for
innodb_use_native_aio=ON.

innodb_linux_aio=auto is equivalent to innodb_linux_aio=io_uring when
it is available, and falling back to innodb_linux_aio=aio when not.

Debian packaging is no longer aio exclusive or uring, so
for those older Debian or Ubuntu releases, its a remove_uring directive.
For more recent releases, add mandatory liburing for consistent packaging.

WITH_LIBAIO is now an independent option from WITH_URING.

LINUX_NATIVE_AIO preprocessor constant is renamed to HAVE_LIBAIO,
analogous to existing HAVE_URING.

tpool::is_aio_supported(): A common feature check.

is_linux_native_aio_supported(): Remove. This had originally been added in
mysql/mysql-server@0da310b69d in 2012
to fix an issue where io_submit() on CentOS 5.5 would return EINVAL
for a /tmp/#sql*.ibd file associated with CREATE TEMPORARY TABLE.
But, starting with commit 2e814d4702 InnoDB
temporary tables will be written to innodb_temp_data_file_path.
The 2012 commit said that the error could occur on "old kernels".
Any GNU/Linux distribution that we currently support should be based
on a newer Linux kernel; for example, Red Hat Enterprise Linux 7
was released in 2014.

tpool::create_linux_aio(): Wraps the Linux implementations:
create_libaio() and create_liburing(), each defined in separate
compilation units (aio_linux.cc, aio_libaio.cc, aio_liburing.cc).

The CMake definitions are simplified using target_sources() and
target_compile_definitions(), all available since CMake 2.8.12.
With this change, there is no need to include ${CMAKE_SOURCE_DIR}/tpool
or add TPOOL_DEFINES flags anymore, target_link_libraries(lib tpool)
does all that.

This is joint work with Daniel Black and Vladislav Vaintroub.
