We didn't correctly handle POLLHUP or POLLERR on win32.  Do it right now

Closes #164

+ some fixes for the relevant documentation

We really shouldn't be kicking around non-static b64_ functions.
Namespace them all and let's be done with it.

Namespace MAX, MIN and ABS from libbson.  None of those should have been
going out over public headers, so we roll that back.

This is a small source compatibility break.

Correctly propogate the fields parameter in copied cursors.  We copied
the bson, but not the flag that indicated that we'd actually set
something.

o We need to pre-include mongoc-config to pick up MONGOC_ENABLE_X
o Comment out implementation for b64_pton as well

Closes #151

This allows building *.[ch] even when libssl and/or libsasl are not available.

This helps get the library to build for iOS, and similarly would be helpful for building the library under any third-party build system.

Sort of an aside: on Mac OS libssl is deprecated. iOS has never shipped with it. On Mac OS the headers are in /usr/include but aren't available when building an iOS project.

Ideally, someday, libmongoc would support both libssl and Common Crypto, Apple's implementation.

Implementation in headers is bad.  Separate out the implementation and
file scoped statics into a .c and pull the necessary function definitions
out into the associated -private.h

Closes #116

bson_concat is a more straight forward memcpy than using bson_value with
iteration.

Closes #147

Renamed the field, and fixed the failure check.
There can only ever be one WriteConcernError, which is a bson object
containing the code (int), errInfo (object) and errmsg (cstring),
so there is no arrays to merge.

Closes #153

Falls back to extracting the subject from the cert for backwards
compatibility

Closes #145

gridfs file seek had incorrect handling for detecting page migration.
Fixed a potential segfault and the underlying conditional.

And adding the host name into the error message when failed.
