This means that when a module is conditionally imported via ifdef
depending on the OS or build flags, the cabal file has to mirror the
same logic there to only list the module then.
Since there are lots of OS's and lots of combinations of build flags
here, it's rather difficult to know if the cabal file has been completelty
correctly updated to match the source code.
So I am very unhappy with needing to update things in two places. I've
only tested this on linux with most build flags enables; this will
probably need significant time and testing to catch every cabal file
tweak that this change to Cabal requires. And it will be a continual
source of compile failures going forward when the code is modified and
the cabal file not also updated.
DRY DRY DRY, I repeat myself, but: DRY! Sigh..
(Also, had to remove all Build.* that are standalone programs from the
Other-Modules list, because since cabal passes those modules to ghc when
building git-annex, it complains that they use module Main. Those
modules are only used when building with the Makefile anyway, so this
change shouldn't break anything.)

Security fix: Disallow hostname starting with a dash, which would get
passed to ssh and be treated an option. This could be used by an attacker
who provides a crafted ssh url (for eg a git remote) to execute arbitrary
code via ssh -oProxyCommand.
No CVE has yet been assigned for this hole.
The same class of security hole recently affected git itself,
CVE-2017-1000117.
Method: Identified all places where ssh is run, by git grep '"ssh"'
Converted them all to use a SshHost, if they did not already, for
specifying the hostname.
SshHost was made a data type with a smart constructor, which rejects
hostnames starting with '-'.
Note that git-annex already contains extensive use of Utility.SafeCommand,
which fixes a similar class of problem where a filename starting with a
dash gets passed to a program which treats it as an option.

Fix the external special remotes git-annex-remote-ipfs,
git-annex-remote-torrent and the example.sh template to correctly support
filenames with spaces.
This commit was sponsored by John Peloquin on Patreon.
External special remotes will refuse to operate on keys with spaces in
their names. That has never worked correctly due to the design of the
external special remote protocol. Display an error message suggesting
migration.
Not super happy with this, but it's a pragmatic solution. Better than
complicating the external special remote interface and all external special
remotes.
Note that I only made it use SafeKey in Request, not Response. git-annex
does not construct a Response, so that would not add any safety. And
presumably, if git-annex avoids feeding any such keys to an external
special remote, it will never have a reason to make a Response using such a
key. If it did, it would result in a protocol error anyway.
There's still a Serializeable instance for Key; it's used by P2P.Protocol.
There, the Key is always in the final position, so it's ok if it contains
spaces.
Note that the protocol documentation has been fixed to say that the File
may contain spaces. One way that can happen, even though the Key can't,
is when using direct mode, and the work tree filename contains spaces.
When sending such a file to the external special remote the worktree
filename is used.
