 * Changed the assignment of values for missing DT_* constants. Since
   the 'd_type' field is of type 'unsigned char' we assign a negative
   number for each missing DT_* constant so they are distinguishable but
   do not collide with the values from the libc implementation.
 * Added a new 'DirStreamWithPath' that contains the path of the
   directory the directory stream belongs to.
 * 'readDirStreamWithType' falls back to a 'stat' if the 'd_type' is
   unknown or undetermined.
 * Added some tests for 'readDirStreamWithType'.

 * Added `readDirStream`/`readDirStream` for ByteString, PosixPath
 * Removed `DirEnt`, `readDirStreamWith`, `readDirStreamWithPtr` from public API

This version of `readDirStreamWith` takes a pre-allocated pointer as an
additional argument that is used to store the pointer to the dirent. It
is useful when you want to read a lot of entries and want to safe a few
allocations since you can reuse the pointer for each call to
`readDirStreamWithPtr`.

This commit exposes the dirent pointer used in the directory stream
functions wrapped in a newtype called `DirEnt`. It also adds a new
function `readDirStreamWith` that takes a callback that is used to
obtain the result from the pointer to the directory entry.

One such platform is Debian unstable armhf, which is in the process of
transitioning to 64-bit time_t: https://wiki.debian.org/ReleaseGoals/64bit-time

On that platform (as well as any other glibc/musl platform), however,
CTimeVal isn't used for anything at all because there are #ifdefs that
prefer using `utimensat` which takes CTimeSpec instead. This fix is
therefore quite theoretical, as it is unknown whether there are any
platforms actually affected.

`musl` defines the `environ` symbol as a weak alias, which on AArch64
requires particular treatment by the compiler. As GHC doesn't have
access to the prototype of the symbol, it doesn't know that this
treatment is necessary and consequently we emit assembly that the linker
will choke on.

See GHC #24011.
