The `time` package has recently moved its primary upstream location
to https://github.com/haskell/time.

This leaves `transformers` the only package used by GHC still requiring
darcs2git mirroring machinery.

Summary:
Previously, the full database stack was used for ghc-pkg to
modify packages, which meant that commands like
'ghc-pkg unregister --user' worked the same as 'ghc-pkg unregister'.
Since package modification is a "read and write" operation, we
should use the flag db stack (which is currently used for reads)
to determine which database to update.

There is also a new flag --user-package-db, which lets you explicitly
set the user database (as seen by --user).  This was mostly added
to aid in testing, but could be useful for end users as well.

Summary:
Previously, the GHC API was "semi" wired-in: it was installed with a
version number, but that version number was hard-coded into the compiler
and it wasn't really possible to install other copies of the GHC API.
This patch makes the GHC API more similar to existing wired-in packages
such as ghc-prim, and will be helpful when we start extending the amount
of information passed to -package-name.

This reverts commit c41b716d.

With the Cabal bump reverted, this should build again, and we aim to
keep it buildable like this.

Summary:
As a security precaution, GHCi helpfully refuses to run a .ghci file if it is owned by another user. But if the that other user is root, then arguably GHCi should not refuse to interpret the file, because if root really was malicious, then the user would be having a bad day anyways.
This means that .ghci files installed in a global location, say under /usr/local/, can now be read.

Fixes #9324

Test Plan:
```
$ sudo touch .ghci
$ ghci
```
Notice that the warning about the file being owned by someone else is now gone.

Summary:
This patch fixes inconsistency in exported functions from TcSplice.lhs and TcSplice.lhs-boot
files. It looks like only GHC HEAD is sensitive to it and complains about it while bootstraping
another HEAD. At least this is what happening on Solaris/AMD64 builder machine where GHC 7.9.20140620
is used as a boostrap compiler. The failure does not happen on another builders.

Summary:
Carl Howells pointed out[0] that the `Monoid` instance for
`Data.Proxy.Proxy` is only defined for types with kind *.

This is a very mild change. Furthermore, Edward Kmett revealed[1] that
it was supposed to be there all along -- the extension simply got lost
in commit 1d1ff77a, as pointed out by
Adam Vogt[2]. This used to be correct in GHC 7.6, so this commit fixes a
regression.

This addresses #9317.
