This leaves git annex unused --from remote still using loggedKeysFor
and buffering more than ought to be necessary, but I can't see a way to
improve that.
In Annex.Branch.branch, the (++) was killing laziness.
Rewrote so it streams lazily.
filterM also kills laziness, so made loggedKeys use a Unchecked type,
and check if the key is dead in the seek loop.
Note that loggedKeysFor still buffers, so git-annex info <remote> and
git-annex unused --from remote still use more memory than necessary.
Also removed some unused functions from Annex.Journal.
Test case is 24 directories each containing files named 1..10000.
The concat and filterM destroyed what laziness there is in
dirContentsRecursive, making it buffer all the filenames. Memory
use was around 300 mb (possibly growing slightly as it progressed).
After this fix, memory use drops to a constant 59 mb.
Note that dirContentsRecursive still buffers the entire content of a
directory (not subdirectories) so this is still not optimal.
runshell followed by git annex webapp didn't install that stuff, because
GIT_ANNEX_APP_BASE is not set. Running git-annex.linux/git-annex-webapp did
install that stuff, since that script set the env var. I noticed this with
the termux port whose instructions currently go that way.
Seems the right thing to do is to move the env var setting to runshell.
Assistant: Integrate with Termux:Boot, so when it's installed, the
assistant is autostarted on boot.

Added some tweaks to make git-annex work in termux on Android. The regular
arm standalone tarball now works in termux.
I guess the test for "$base/bin/git" is not really necessary, since it
tests for git-annex. Since that gets deleted on android, removed that test.
These are pretty hackish hacks, especially adding it to PATH. The goal is
to make it work well enough out of the box on Android.

Preloaded libraries from the host system may not get along with the bundled
linker.
This was observed by users in termux:
ERROR: ld.so: object '/data/data/com.termux/files/usr/lib/libtermux-exec.so' from LD_PRELOAD cannot be preloaded (wrong ELF class:
ELFCLASS64): ignored.
Bad system call
But it could also affect more usual systems; the preloaded library might rely
on symbols from the host libc that are not available or have the wrong versions
in the bundled libc. Unsetting LD_PRELOAD entirely seems safest.
Switch to Data.Map.Strict everywhere that used it.
There are still lots of lazy maps in git-annex. I think switching these
is safe. The risk is that there might be a map that is used in a way
that relies on the values not being evaluated to WHNF, and switching to
strict might result in bad performance or memory use. So, I have not
switched everything.
