[PATCH v3 0/6] manual: Document several *at file system interface functions

[Arjun Shankar]

This patch series adds info documentation for faccessat, mkdirat, renameat,
unlinkat, and utimensat (along with the related futimens).

They are marked AC-Unsafe and AS-Unsafe since they have not been audited for
these properties.

v2: https://sourceware.org/pipermail/libc-alpha/2025-January/163522.html

Changes in v3:
 * Address Florian's comments:
 * Add a list of common errors in the "Descriptor-Relative Access" section.
 * Drop EBADF, EINVAL (specifically caused by invalid flags) and ENOTDIR
   error descriptions from the function entries and refer to the
   "Descriptor-Relative Access" section instead.
 * Clarify EISDIR for unlinkat.
 * Use correct (xref) reference to Time Types in futimens.
 * Document an futimens equivalent utimensat call.
 * Correct EINVAL description for utimensat (I tested this a bit).
 * Correct ENOENT description for utimensat.
