Reviewers

This introduces djblets.util.functional, which offers two useful
functions:

  • iterable_len(): Efficiently computes the length of a finite
    iterable.

  • lazy_re_compile(): Lazily compiles a regex on first access, reducing
    module load time for regexes as class/module attributes.

Unit tests pass.

Used both of these in some in-progress code.
