This patch adds support for Android's logging subsystem in Tor. When
debugging Android applications it is useful to be able to collect
information about the application running on the platform via the
various system services that is available on the platform.
This patch allows you to add "Log notice android" to your torrc and have
Tor send everything above and including the notice severity to Android's
ring buffer which can be inspected using the 'adb logcat' program.

Modified -Wnormalized flag to nfkc option in configure.ac to avoid source code

Previously we would detect the system openssl on OSX, and then fail
to use it, since we required Open 1.0.1 or later. That's silly!
Instead of looking for RAND_add(), look for TLSv1_1_method(): it was
introduced in 1.0.1, and is also present in LibreSSL.
Also, add the hombebrew path to our search path here.
Fixes bug 23602; bugfix on 0.2.7.2-alpha.
Add a detection for the KIST scheduler in our build system and set

The GNU C Library (glibc) offers an function which allocates the
necessary memory automatically [0]. When it is available, we use that.
Otherwise we depend upon the `getcwd` function which requires a
preallocated buffer (and its size). This function was used incorrectly
by depending on the initial buffer size being big enough and otherwise
failing to return the current working directory. The proper way of
getting the current working directory requires a loop which doubles the
buffer size if `getcwd` requires it. This code was copied from [1] with
modifications to fit the context.
