This allows lines such as the following to exist in requirements files:
INITools==0.2 --install-options="--prefix=/opt"
virtualenv>=1 --global-options="--no-user-cfg"
In addition, the requirements file parser was overhauled with simplicity
and clarity in mind.
This speeds up the _filter_install function that is used to filter the
output of `python setup.py install` when installing packages. It does
this by using a single regex which is pre-compiled and thus avoiding a
`for` loop over 15 different regexes.

If an exact version is specified for install, and that version is
already installed, then there is no point going to pypi as no install
is needed.
Adds a test called
`test_upgrade_no_look_at_pypi_if_exact_version_installed`.
This is a rework of PR #771, because that PR is old and has merge
conflicts that were easier to fix by applying the changes manually.
Without this, I was getting:
$ pip install -U 'sentry[lol]'
...
UnknownExtra: Unknown 7.4.1 has no such extra feature 'lol'
With this, I get:

use pkg_resources.Distribution.requires instead of
Requirements.requirements to have environment markers parsing for free
It also unifies a little the process for wheel and non-wheel installs
closes#2174
It's now possible to specify requirements markers in requirements.
Examples::
futures; python_version < '2.7'
mock; python_version < '3.3'
nose
ordereddict; python_version < '2.7'
unittest2; python_version < '2.7'
The separator is "; ". For convinience, ";" alone is also supported, but
no in URLs. The ";" character is a legit and common character in an URL.
Example of valid URL without markers::
http://foo.com/?p=bar.git;a=snapshot;h=v0.1;sf=tgz
Example of URL with markers::
http://foo.com/?p=bar.git;a=snapshot;h=v0.1;sf=tgz; python_version < '3.3'
Default from pip 1.6 will be to always use wheels, so the --use-wheels
in requirements.txt is now deprecated. However, the --no-use-wheels
is introduced to be able to disable wheel usage via requirements.txt.
* Deprecates the --download-cache option & removes the download
cache code.
* Removes the in memory page cache on the index
* Uses CacheControl to cache all cacheable HTTP requests to the
filesystem.
* Properly handles CacheControl headers for unconditional
caching.
* Will use ETag and Last-Modified headers to attempt to do a
conditional HTTP request to speed up cache misses and turn
them into cache hits.
* Removes some concurrency unsafe code in the download cache
accesses.
* Uses a Cache-Control request header to limit the maximum
length of time a cache is valid for.
* Adds pip.appdirs to handle platform specific application
directories such as cache, config, data, etc.

Additional work - refactored tests to new style.
* Better output with the bare asserts we use throughout the tests
* Function fixtures are pretty nice, especially as a way to
start a background server or create an isolated virtualenv
