The Linux fs.protected_regular sysctl setting could cause rsync to fail to write a file in-place with the O_CREAT flag set, so the code now tries an open without O_CREAT when it might help to avoid an EACCES error. A testsuite script is included (and slightly improved by Wayne to ensure that it outputs a SKIP when fs.protected_regular is turned off).
Some hosts were not running `mkgitver` when they should, so tweak the
script to only update the timestamp when the file's data changes and
then always run the script when performing a build.
In 2004, an allocation optimization has been added to the file
list handling code, that preallocates 32k of file_struct pointers
in a file_list. This optimization predates the incremental
recursion feature, for which it is not appropriate anymore. When
copying a tree containing a large number of small directories,
using the incremental recursion, rsync allocates many short
file_lists. Suddenly, the unused file_struct pointers can easily
take 90-95% of the memory allocated by rsync.
- Make SIMD & ASM only default to enabled on linux for now (due to
FreeBSD & MacOS issues).
- Improve the enable/disable help messages so that they don't look
wrong when the opposite --enable-X/--disable-X arg is specified.
- use `grep -E` and `grep -F` (`egrep` and `fgrep` are non-standard)
- use same hashbang style for all test scripts
- use explicit comparisons in test scripts
- remove redundant ; from test scripts
- make test script not executable, just like all the other scripts
- unify codestyle across all test scripts
- make openssl license exception clearer by having it at the top
- use modern links in COPYING. The text now matches:
https://www.gnu.org/licenses/gpl-3.0.txt
- fix typo
* Eventually add write permission when setting extended attributes
When we need to set extended atributes of file which does not
allow write then temporarily add write permission and after
attributes are set, remove it again.

Legacy configure behaviour was to detect IPv6 support through known IPv6
capable version of common standard libraries. Now: it runs a POSIX test
to determine if IPv6 is usable (in case it has not been disabled).
