Implements the posix-specified strftime conversions for the default locale, along with comprehensive unit tests. This reuses a lot of design from printf, as well as the printf writer. Roughly based on #111305, but with major rewrites.
libc Documentation ================== The libc documentation is written using the Sphinx documentation generator. It is currently tested with Sphinx 1.1.3. To build the documents into html configure libc with the following cmake options: * -DLLVM_ENABLE_SPHINX=ON * -DLIBC_INCLUDE_DOCS=ON After configuring libc with these options the make rule `docs-libc-html` should be available.
