Merge branch 'jc/noop-with-static-inline'

A no-op replacement function implemented as a C preprocessor macro
does not perform as good a job as one implemented as a "static
inline" function in catching errors in parameters; replace the
former with the latter in <git-compat-util.h> header.

* jc/noop-with-static-inline:
  compat-util: type-check parameters of no-op replacement functions
