Added a check for 'getvalue' attr, calling it to retrieve the length if we can.
We also try/except the fileno() call, which can throw
io.UnsupportedOperation for BytesIO because, well, they're not files.
This has the added benefit of including proxies defined by the OS X System Configuration framework and in the Windows registry, rather than only checking os.environ.
Fixes#649 and #1329 by making Session.headers a CaseInsensitiveDict,
and fixing the implementation of CID. Credit for the brilliant idea
to map `lowercased_key -> (cased_key, mapped_value)` goes to
@gazpachoking, thanks a bunch.
Changes from original implementation of CaseInsensitiveDict:
1. CID is rewritten as a subclass of `collections.MutableMapping`.
2. CID remembers the case of the last-set key, but `__setitem__`
and `__delitem__` will handle keys without respect to case.
3. CID returns the key case as remembered for the `keys`, `items`,
and `__iter__` methods.
4. Query operations (`__getitem__` and `__contains__`) are done in
a case-insensitive manner: `cid['foo']` and `cid['FOO']` will
return the same value.
5. The constructor as well as `update` and `__eq__` have undefined
behavior when given multiple keys that have the same `lower()`.
6. The new method `lower_items` is like `iteritems`, but keys are
all lowercased.
7. CID raises `KeyError` for `__getitem__` as normal dicts do. The
old implementation returned
6. The `__repr__` now makes it obvious that it's not a normal dict.
See PR #1333 for the discussions that lead up to this implementation
As per #1105, certifi is being end-of-lifed. Requests will use either
its own vendored bundle, or possibly (when packaged with OS distributions)
an externally packaged bundle, which can be enabled by patching
requests.certs.where().
This will permit the deletion of just that one file in order
to fall back to the [probably more accurate but less consistent]
Distro provided CA certs.
JSON *must* be encoded using UTF-8, UTF-16 or UTF-32 (see the [RFC][1]; detect the encoding based on the fact that JSON always starts with 2 ASCII characters.

compat.py: relevant imports added
utils.py: then those imports are imported here.
Nothing else was changed, but I saw mentions of quoting later in
utils.py but I wasnt sure what to do about that.
This allows iter_content and iter_lines to succeed without
crashing even after the response content has been fetched
(iter_content gives you an iterator over the prefetched
content)
It uses the same logic whenever we're trying to use a list of key values and
avoid what I had started doing -- using the same pattern everywhere.
proxies, and headers should both be covered by this commit.
