Add in-kernel file copying for several platforms. (#1092) 
* Add in-kernel copying support for Linux (sendfile64(2), copy_file_range(2)), FreeBSD 13 (copy_file_range(2)), MacOS (copyfile(2)), and Windows (CopyFileExA).

* Fix macro name USE_COPY_FILE_RANGE.

* Minor bugfixes for userspace fallback.

* Fix linux sendfile64 bugs.

* Remove some overzealous asserts.

* Allow transmission-test-copy to take an optional argument for an external reference file.

* Fix return value error of tr_sys_path_copy.

* Use COPYFILE_ALL for Macs without COPYFILE_CLONE.

* Add in-kernel file copying for several platforms.

Numerous operating systems now have support for copying files directly in the
kernel, which is generally more efficient than copying in a userspace read(2)/
write(2) loop. (This becomes particularly relevant for 4th gen PCI-E storage,
which approaches the latency of DRAM.) For Linux I use sendfile64(2), and, for
later kernels, copy_file_range(2). FreeBSD 13 will also support
copy_file_range(2). MacOS has copyfile(2), and Windows has CopyFileExA.
Operating systems lacking such a syscall continue to use the existing
read(2)/write(2) loop.

* Appease uncrustify.

* Appease uncrustify.

* copy-test: generate random content at run time.

* copy-test: Stylistic changes and more check()s.

* copy-test: files_are_identical should follow test idioms

* tr_sys_path_copy: numerous tweaks as requested by review.

* s/old file/source file; s/new file/destination file.

* tr_sys_path_copy: handle win32 wide characters in paths.

* Uncrustify.

* test-copy: Use non-string create_file_with_contents.

* tr_sys_path_copy: numerous fixes.

Per review: generate test file content at runtime; tidy use of check();
fix style; re-measure file sizes in the copy; define a macro when the
system does not provide it; use Unicode APIs on Windows; and fix
documentation.

* Updated as per comments.

* Rebase kernel-copy changes onto 3.0 with gtest.

* Undo irrelevant comment change.

* Fix syntax error.

* Use tr_malloc() instead of tr_valloc().

* Use EXPECT instead of TR_ASSERT in gtest.

* Add error handling.

* Acceptable coding style has changed again.

Now it's camelCase. Also use nullptr instead of NULL, etc.

* Fix east/west const.
