Fixes a regression introduced by Homebrew/homebrew#47950 in 9e3ee3e causing build
failures with the error
cabal: The file does not exist ''.
This will occur whenever the optional :flags key isn't in the options
hash passed to install_cabal_package.

To address issue Homebrew/homebrew#47346 (git-annex-webapp missing), we explicitly
enable the "webapp" flag for git-annex. This should prevent git-annex
from being built without the webapp and make the build fail if there is
e.g. a dependency issue.

The default max-backjumps can be too low, especially since
Language::Haskell::Cabal doesn't guarantee an LTS config.
In particular, this fixes a git-annex build failure in Homebrew/homebrew#47950ClosesHomebrew/homebrew#49158.

Removes the need to call setup_ghc_compilers in every Haskell language
formula, by automatically calling fails_with.
Adds a :home option to the cabal_sandbox method. This option allows a
specific temporary HOME to be used instead of the current working
directory, and in turn allows a single Cabal package database to be reused
between multiple calls to this method.
Avoids updating the Cabal package database more than once if cabal_sandbox
is called multiple times.
Removes the need to call cabal_clean_lib whenever cabal_sandbox is called,
by automatically cleaning the lib directory.
Adds a :keep_lib option to the cabal_sandbox method. This option allows
opting out of the automatic cleaning.
Ensures build products are always removed from the current working
directory.
Removes a workaround for versions of cabal-install older than 1.20.0.0.
Adds a cabal_sandbox_add_source method.
Adds a :using option to the install_cabal_package method. This option
allows specifying the Haskell language tools that are required to install
a particular formula, and in turn allows formulae to be simplified by
replacing calls to multiple methods with a single call to this method.
Allows customizing the call to install_cabal_package by giving a block.
Removes empty method shells.

installing git-annex with cabal-install is quite long and requires to install
some heavy packages. It also has several external lib dependencies and needs a
few configuration flags to build so it is quite difficult to install too.
This formula should make it easy and quick to install with a bottle.
The huge number of haskell dependencies is built within the formula and statically
linked to git-annex. The haskell libraries built are discarded - cabal-install
should be used instead of this package in order to keep them.
