* Set execute bit on files if and only if they begin with (#!).
Git only tracks the 'x' (executable) bit on each file. Prior to this
CL, our files were a random mix of executable and non-executable.
This change imposes some order by making files executable if and only
if they have shebang (#!) lines at the beginning.
We don't have any executable binaries checked into the repo, so
we shouldn't need to worry about that case.
* Added fix_permissions.sh script to set +x iff a file begins with (#!).
* Remove protoc release for 32-bit Macs
Apple has been removing the support for 32-bit Mac apps: https://support.apple.com/en-us/HT208436
Our release infrastructure no longer supports building for 32-bit architecture.
* Remove protoc artifact for MacOS 32-bit
This was fairly straightforward using the existing build-protoc.sh
script. The only problem I ran into was that the x86 Docker builds
create output directories owned by root, which caused some permission
issues. Fortunately it was easy to get around that just by doing those
Docker builds last.
This configuration builds both 32-bit and 64-bit binaries for Mac OS X.
One thing I had to change was to increase our minimum supported version
for 10.7 to 10.9, because 10.9 (Mavericks) appears to be the earliest
version supporting C++11.
