Conor Hennessy eba01d1119 Remove usage of gorest.
Due to on going issues, we've decided to remove gorest. It started with gorest
not being thread-safe (it does introspection to create a new handler which is
an easy process to mess up with multiple threads of execution):
    https://code.google.com/p/gorest/issues/detail?id=15
While the issue has been marked fixed, it looks like the patch has introduced
more problems than the original issue and simply doesn't work properly.
I'm not sure the behaviour was thought through properly. If a new instance is
needed every request then a handler-factory is needed or the library needs to
set expectations about how the new objects should interact with their
constructor state.
While it was tempting to try out another routing library, I think for now
it's better to use dumb vanilla Go routing. At least until we decide which
URL format we intend to standardize on.

Julius Volz 6ea22f2bf9 Add compaction regression tests.
This adds regression tests that catch the two error cases reported in

  https://github.com/prometheus/prometheus/issues/367

It also adds a commented-out test case for the crash in

  https://github.com/prometheus/prometheus/issues/368

but there's no fix for the latter crash yet.

Conor Hennessy 2d2c434d48 More updates for first time users.
- Modified sample conf so it is useable by default, also added some
      comments from the 'hello world' configuration.
    - Updated README so there's a clear two step start for newbies.
    - Added extra vim swap files to gitignore.

Matt T. Proud 4a87c002e8 Update low-level i'faces to reflect wireformats.
This commit fixes a critique of the old storage API design, whereby
the input parameters were always as raw bytes and never Protocol
Buffer messages that encapsulated the data, meaning every place a
read or mutation was conducted needed to manually perform said
translations on its own.  This is taxing.

Matt T. Proud 12d5e6ca5a Curation should not starve user-interactive ops.
The background curation should be staggered to ensure that disk
I/O yields to user-interactive operations in a timely manner. The
lack of routine prioritization necessitates this.

Matt T. Proud 0d73b8f87e Adjust curation thresholds and intervals.
Curation is an expensive process.  We can perform it less frequently;
and in the case of compaction processors, we can afford to let them
group more together.
