Currently, the error.rs's errno import is done manually by copying the comments from include/linux/errno.h and uses the declare_err! to wrap the constant errno. However, this reduces the readability and increases difficulty of maintaining the error.rs if the errno list is growing too long or or if errno.h gets updated for new semantics. This patchset solves this issues for good by introducing a rule to generate errno_generated.rs by seding the errno.h and including the generated file in the error.rs. This patch is based on the rust-next branch.
