Don't suppress errors when executing mach bootstrap processes.
[Omitting an argument](https://docs.python.org/2/library/sys.html#sys.exit) to sys.exit causes it to default to 0, so buildbot doesn't report it as an error.
We were just lucky that the android builders happened to have a build step that failed that didn't rely on running python!

fix(capture_webrender): try fallback capture dir
<!-- Please describe your changes on the following line: -->
This PR try to update behavior of webrender capture to have fallback dir - first it try to create under current working dir, if fails go back to $TMPDIR. I was debating between TMP vs $home, bit hesitate to create some folder under user's home dir directly so choose TMP instead. Can be easily changed, or add few more if needed.

0 is not among the valid values for a wrap mode or filter, so it won't
ever be returned unless the driver is broken, and even if it was a
valid value we would want to pass it through.

Style change in display_list/builder.rs to reduce
the number of & and * found in the code.
Rect<Au> are basically 4 integers so there is no
need to pass by reference.
Always use border_padding and writing_mode from the same fragment.
Mixing them will trigger a debug assertion if the writing modes are different.
Cleanup and use compute_background_clip
It seems that the result of hash algorithm used in bloom filter depends
on the pointer length. On 64bit platforms, there are 135 false positives
in the first part of that test, and 8 in the second part. However, on
32bit platforms, the numbers become 157 and 16 correspondingly.
16 is still less than 20% in the second part, so all fine, but 157 is
slightly larger than 15% in the test assertion. Given it is what we are
shipping, we probably should just accept this and loosen the assertion.

Inserting a lot of rules in the root level is super-inefficient. This fixes it
by not doing it.
It gives the root rule node to the style, but that's fine, since it's useless.
All this code-path is already pretty messy.

It's not sound to insert random matrices in random positions in the transform
operation list.
I cannot make any sense of what the old code was trying to do.
