* The getLine and getColumn functions need to update the position, or
they will return stale data for buffered streams. This fixes a bug in
the clang -analyzer-checker-option-help option, which was not wrapping
the help text correctly when stdout is not a TTY.
* If the stream contains multi-byte UTF-8 sequences, then the whole
sequence needs to be considered to be a single character. This has the
edge case that the buffer might fill up and be flushed part way
through a character.
* If the stream contains East Asian wide characters, these will be
rendered twice as wide as other characters, so we need to increase the
column count to match.
This doesn't attempt to handle everything unicode can do (combining
characters, right-to-left markers, ...), but hopefully covers most
things likely to be common in messages and source code we might want to
print.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

clang-format (https://reviews.llvm.org/D33932) to keep primary headers
at the top and handle new utility headers like 'gmock' consistently with
other utility headers.
No other change was made. I did no manual edits, all of this is
clang-format.
This should allow other changes to have more clear and focused diffs,
and is especially motivated by moving some headers into more focused
libraries.

- The current_pos function is supposed to return all the written bytes, not the
current position of the underlying stream.
- This caused tell() to be broken whenever the underlying stream had buffered
content.
