Also replace lseek64 with lseek.
_FILE_OFFSET_BITS=64 is passed to needed platforms since configure uses
AC_SYS_LARGEFILE macro. Therefore off_t is already 64-bit and lseek is
same as lseek64.
Additionally this fixes buils with latest musl where these lfs64
functions are moved out from _GNU_SOURCE and under _LARGEFILE64_SOURCE
macro alone. This makes the builds fail on 32-bit platforms even though
default off_t on musl is 64-bit always.

The mapper test program writes audio data frame to files, and read
them from the files, then validate them. For the operations, usage of
any in-memory file is good to shorten time of overall operations.
This commit uses shm by memfd_create().

In mapper test program, two set of file descriptors open to the same files
for container builder and parser contexts, however the same file descriptor
is available for the case.
This commit arranges to use the same file descriptor for the contexts.

This commit closes file descriptor outside of container module so
that maintenance of lifetime for the descriptor is delegated to container
user.

Internal container module operates file descriptor to media file. For
this purpose, the structure has fd member and any file operation is done
internally. However, the case to use special file descriptor such as
memfd requires to maintain file descriptor externally.
This commit opens file descriptor outside of container module. The
internal APIs to initialize container get an argument for the file
descriptor instead of file path.

In system V ABIs with ILP32 data model, bit shift for '1ul' can brings
undefined behaviour when the calculation result is over 32 bit width.
This commit fixes the bug.

In former commits, mapper module gets supports of muxer/demuxer for
single/multiple targets for playback source or capture destination. This
commit adds a unit test for them. This includes positive test cases only.
The test cases actually generate I/O to file systems for many test cases.
It takes a bit long time to finish.
