when we open a file that we don't expect to be a symlink use
O_NOFOLLOW to prevent a race condition where an attacker could change
a file between being a normal file and a symlink
Replace unsafe generic function pointer cast with proper type cast for
qsort() comparison function. This fixes a potential type mismatch
warning without changing the behavior.

rsbackup (https://github.com/ewxrjk/rsbackup) uses "ssh <host> true" to
check that the host in question is reachable. I like to configure my
backed-up hosts to force the backup system to go via `rrsync`, but I
always have to add a local tweak to allow `SSH_ORIGINAL_COMMAND=true` to
work. I think this would be safe enough to include in rrsync.
Clang rightfully complains about conflicting prototypes, as both lseek() variants
are redefined:
syscall.c:394:10: warning: a function declaration without a prototype is deprecated
in all versions of C and is treated as a zero-parameter prototype in C2x, conflicting
with a previous declaration [-Wdeprecated-non-prototype]
off64_t lseek64();
^
/usr/include/unistd.h:350:18: note: conflicting prototype is here
extern __off64_t lseek64 (int __fd, __off64_t __offset, int __whence)
^
1 warning generated.
The point of the #ifdef is to build for the configured OFF_T; there is
no reason to redefine lseek/lseek64, which should have been found
via configure.

Clang rightfully complains about invoking bomb(..) without a proper prototype:

Building with clang-16 complains with:
./simd-checksum-x86_64.cpp:204:25: warning: passing 1-byte aligned argument to
16-byte aligned parameter 1 of '_mm_store_si128' may result in an unaligned pointer

Since 05278935 (- Call mkdir_defmode() instead of do_mkdir(). - Define
orig_umask in this file, not options.c. - Made orig_umask a mode_t, not an
int., 2006-02-24), the type for the global was changed, and therefore on
systems where sizeof(mode_t) != sizeof(int), writes or reads to them will
overflow to adjacent bytes.
Change the type to the one used everywhere else and avoid this problem.
While at it, silence again a warning that is being triggered by
Apple's clang 15.
- Put sum2_array into sum_struct to hold an array of sum2 checksums
that are each xfer_sum_len bytes.
- Remove sum2 buf from sum_buf.
- Add macro sum2_at() to access each sum2 array element.
- Throw an error if a sums header has an s2length larger than
xfer_sum_len.
- Change the developer flow to not require updating the git-version repo
that the builds used to download a git-version.h file. The Actions now
do a full repo fetch so that the .h file can be generated via the git
history.
- Get rid of the gensend Makefile target that was used for the above.
- Get rid of the pre-push git hook file that called "Make gensend".
- Change the FreeBSD build to save an artifact with its built binaries.
