pkg/csource: add call argument annotations to generated C-source files

The structure of arguments passed into syscalls is often hard to parse
since it is memcpy'd into mmap'd regions. Structural relations are often
lost in translation, resulting in reproducers that take longer for a
developer to understand.

This patch adds functionality for parsing syscall arguments semantically and
emitting a structured and human-readable comment which is inserted before each
syscall in the resulting C-source.
