Subject: [PATCH 1/7] musl: Reorganize some statfs-related types for a cleaner
 diff

This moves similar types together (e.g. statfs and statfs64) so removing
them is cleaner.

Subject: [PATCH 2/7] musl: Unify definitions of `siginfo_t`

Musl provides a single definition for `siginfo_t` [1] with the order of
`si_code` and `si_errno` controlled by `__SI_SWAP_ERRNO_CODE`. This is
only set on mips (both 32- and 64-bit).

[1]: https://github.com/kraj/musl/blob/ffb23aef7b5339b8c3234f4c6a93c488dc873919/include/signal.h#L99-L147

[ extracted from "Remove all redundant definitions in musl backend", add
  context to the commit message - Trevor ]

Subject: [PATCH 3/7] musl: Unify definitions of statvfs and statvfs64

`statvfs` already exists in `musl/mod.rs`. Use that were possible and
move a common version of `statvfs64` there.

[ reduce this patch to only cover statvfs*, leaving statfs as a separate
  change - Trevor ]

Subject: [PATCH 4/7] musl: Unify definitions of statfs and statfs64

Only mips uses a special statfs(64)

[ squash "Use `#[cfg]` blocks to special-case statfs on mips", change
  this patch to only cover statfs and statfs64, include part of "Remove
  new redundant definitions" - Trevor ]

Subject: [PATCH 5/7] musl: Remove redundant definitions

These types are redundant as they are exported from higher-level
modules.

[ move some non-statfs fixups here from other commits in the series, add
  context to the commmit message - Trevor ]
