## Summary This PR adds `<mntent.h>` with `setmntent()`, `getmntent()`, `getmntent_r()`, `addmntent()`, `endmntent()` and `hasmntopt()`, which programs use to list the mounted file systems. `MOUNTED` is `/proc/fs/mount`, the list that procfs keeps. `getmntent_r()` reads its `<mount point> type <type>` lines, and also the usual fstab and mtab format (`<fsname> <dir> <type> [<options> [<freq> [<passno>]]]`). ## Impact New header and functions, no new option. They are in the static C library, so a program that does not call them does not grow. ## Testing `qemu-armv8a:knsh` with a virtio 9P share mounted at `/mnt`, QEMU 11. The test program was built outside the tree against the export package. A program that lists `MOUNTED` with `getmntent()` and checks the options with `hasmntopt()`. Before, it does not compile (`mntent.h: No such file or directory`). After: ``` v9fs on /mnt type v9fs (rw) rw procfs on /proc type procfs (rw) rw hostfs on /system type hostfs (rw) rw ``` Builds with `-Wno-cpp -Werror`: `qemu-armv8a:knsh`, `lm3s6965-ek:qemu-flat`, `mps2-an500:nsh`, `rv-virt:knsh`, `raspberrypi-pico:nsh`. `tools/checkpatch.sh -c -u -m -g` passes. -- This is an automated message from the Apache Git Service.
