Running the Python style guide checker
[`pep8`](https://pypi.python.org/pypi/pep8) on the Python code headers
in this repository results in the following error being emitted:
$ pep8 utils/build-script
utils/build-script:1:1: E265 block comment should start with '# '
utils/build-script:3:1: E266 too many leading '#' for block comment
utils/build-script:5:1: E266 too many leading '#' for block comment
utils/build-script:6:1: E266 too many leading '#' for block comment
utils/build-script:8:1: E266 too many leading '#' for block comment
utils/build-script:9:1: E266 too many leading '#' for block comment
utils/build-script:11:1: E265 block comment should start with '# '
utils/build-script:11:80: E501 line too long (80 > 79 characters)
The problem is that the code header used in most Python files in the
repository:
1. Do not place a space in between `#` and the rest of the comment.
2. Contains some lines that just barely exceed the recommend length
limit.
In addition, not all code headers in the repository follow the same
template.
This commit moves all Python code headers to the following template:

Adds a try/catch block to utils/SwiftBuildSupport.py to catch
ConfigParser.InterpolationMissingOptionError exceptions caused by
missing required preset options. Stores all missing options to
print before exit(1) in get_preset_options().
This default would never actually be used, because if you did check out your
Swift sources there it would look like a normal Swift checkout and we would
infer SWIFT_SOURCE_ROOT from that.
Also, clean up some comments based on suggestions from Dave.
Swift SVN r24606
SWIFT_SOURCE_ROOT is now auto-detected from the location of the build script
files. It looks for the following layouts:
$SWIFT_SOURCE_ROOT/<LLVM_CHECKOUT>/tools/<SWIFT_CHECKOUT>/utils/build-script
$SWIFT_SOURCE_ROOT/<SWIFT_CHECKOUT>/utils/build-script
and defaults back to ~/src/s (as before) if neither of those matches.
SWIFT_BUILD_ROOT now defaults to $SWIFT_SOURCE_ROOT/build, rather than
~/build/swift.
