* replication hooks: role change, master link status, replica online/offline
* persistence hooks: saving, loading, loading progress
* misc hooks: cron loop, shutdown, module loaded/unloaded
* change the way hooks test work, and add tests for all of the above
startLoading() now gets flag indicating what is loaded.
stopLoading() now gets an indication of success or failure.
adding startSaving() and stopSaving() with similar args and role.
* Introduce a connection abstraction layer for all socket operations and
integrate it across the code base.
* Provide an optional TLS connections implementation based on OpenSSL.
* Pull a newer version of hiredis with TLS support.
* Tests, redis-cli updates for TLS support.

The content comes from the definition of the sigcontext and tested on
my aarch64 server.
sigcontext defined at the linux kernel code:
arch/arm64/include/uapi/asm/sigcontext.h
jemalloc 5 doesn't immediately release memory back to the OS, instead there's a decaying
mechanism, which doesn't work when there's no traffic (no allocations).
this is most evident if there's no traffic after flushdb, the RSS will remain high.
1) enable jemalloc background purging
2) explicitly purge in flushdb
__x86_64__ is defined on the on the x32 architecture and the conditionals in
debug.c therefore assume the size of (void*) etc:
debug.c: In function 'getMcontextEip':
debug.c:757:12: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
return (void*) uc->uc_mcontext.gregs[16]; /* Linux 64 */
^
debug.c: In function 'logRegisters':
debug.c:920:21: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
logStackContent((void**)uc->uc_mcontext.gregs[15]);
We can remedy this by checking for __ILP32__ first. See:

and will not be inconsistent after we call debug loadaof.
Before this commit, there were 2 problems:
1, When appendonly is set to no and there is not a appendonly file,
redis-server will crash if we call DEBUG LOADAOF.
2, When appendonly is set to no and there is a appendonly file,
redis-server will hold different data after loading appendonly
file.
The main change introduced by this commit is pretending that help
arrays are more text than code, thus indenting them at level 0. This
improves readability, and is an old practice when defining arrays of
C strings describing text.
Additionally a few useless return statements are removed, and the HELP
subcommand capitalized when printed to the user.
