git-annex find is now RawFilePath end to end, no string conversions.
So is git-annex get when it does not need to get anything.
So this is a major milestone on optimisation.
Benchmarks indicate around 30% speedup in both commands.
Probably many other performance improvements. All or nearly all places
where a file is statted use RawFilePath now.
Finally builds (oh the agoncy of making it build), but still very
unmergable, only Command.Find is included and lots of stuff is badly
hacked to make it compile.
Benchmarking vs master, this git-annex find is significantly faster!
Specifically:
num files old new speedup
48500 4.77 3.73 28%
12500 1.36 1.02 66%
20 0.075 0.074 0% (so startup time is unchanged)
That's without really finishing the optimization. Things still to do:
* Eliminate all the fromRawFilePath, toRawFilePath, encodeBS,
decodeBS conversions.
* Use versions of IO actions like getFileStatus that take a RawFilePath.
* Eliminate some Data.ByteString.Lazy.toStrict, which is a slow copy.
* Use ByteString for parsing git config to speed up startup.
It's likely several of those will speed up git-annex find further.
And other commands will certianly benefit even more.
13.27 failed on OSX:
Undefined symbols for architecture x86_64:
"_utimensat", referenced from:
_c7zP_info in libHSunix-2.7.2.2.a(Files.o)
Which seems likely to be a compilation problem?
The cabal file does not yet demand this version because it's not in Debian
yet and only affects use of certian broken http servers, but let's use it
when it's easily available.
Like with the network-uri split, cabal will automatically turn off the flag
when building with an old network.
I have not tested building with the new network-3.0.0.0 yet; several
other dependencies including aws are still pinned on network-2.*
And added stack-lts-9.9.yaml to support old versions of stack.
The i386 ancient autobuilder needs stack-lts-9.9.yaml; the OSX autobuilder
may also use it for a while, and it's needed to build on eg debian stable.
Running git-annex linux builds in termux seems to work well enough that the
only reason to keep the Android app would be to support Android 4-5, which
the old Android app supported, and which I don't know if the termux method
works on (although I see no reason why it would not).
According to [1], Android 4-5 remains on around 29% of devices, down from
51% one year ago.

This is a rather large commit, but mostly very straightfoward removal of
android ifdefs and patches and associated cruft.
Also, removed support for building with very old ghc < 8.0.1, and with
yesod < 1.4.3, and without concurrent-output, which were only being used
by the cross build.
Some documentation specific to the Android app (screenshots etc) needs
to be updated still.

Test suite is always included.
Building with this flag disabled has actually been broken for some time,
since Command.TestRemote uses tasty. Fewer build flags are better, so good
time to drop it.

esqueleto finally got fixed, thanks to @bitemyapp
Since XMPP was removed, the previous build failures related to it should
no longer be a problem either.
Meanwhile, lts-5.18 fails to build anymore on Debian due to linker
hardening breaking the version of ghc stack uses with that version.

I've long considered the XMPP support in git-annex a wart.
It's nice to remove it.
(This also removes the NetMessager, which was only used for XMPP, and the
daemonstatus's desynced list (likewise).)
Existing XMPP remotes should be ignored by git-annex.

This reverts commit e181603103.
This broke the i386ancient autobuilder due to its use of
--flag git-annex:XMPP --flag=git-annex:dbus
-- Failure when adding dependencies:
fdo-notify: needed ((>=0.3)), stack configuration has no specified version
(latest applicable is 0.3.1)
gnutls: needed ((>=0.1.4)), stack configuration has no specified version
(latest applicable is 0.2)
network-protocol-xmpp: needed (-any), stack configuration has no specified
version (latest applicable is 0.4.8)
OSX autobuilder also seems hosed by it, so too soon.
De-revert later..
