string to enum

[fjhenigman]

A "string to enum" function (inverse of waffle_enum_to_string) would help with writing command line parsing code. For example:
if (argv[1] starts with "WAFFLE_PLATFORM_")
platform = waffle_string_to_enum(argv[1])
else
print usage
This way when waffle grows new platforms, they can be used without having to update any code.
If there are no objections I can write this.

No objections. Please go ahead.

The function seems fine, but a tool that has a command line parameter of WAFFLE_PLATFORM_FOO seems a bit silly. I prefer -p foo / --platform=foo like wflinfo has.

In https://github.com/jljusten/waffle/tree/wflgears, I was trying to separate out the wflinfo command line parsing to use it in a new wflgears tool. (But, the branch has stalled for some months now...)
