Add new gets_s(3) stdio function. This implements the gets_s(3) function as documented at http://en.cppreference.com/w/c/io/gets. It facilitates the optional removal of gets(3). Reviewed by: ed Relnotes: yes Differential Revision: https://reviews.freebsd.org/D12785

Fix setrlimit_test:setrlimit_memlock when the system has exceeded vm.max_wired. This uses the same fix as r294894 did for the mlock test. The code from that commit is moved into a common object file which PROGS supports building first. Sponsored by: Dell EMC Isilon Differential Revision: https://reviews.freebsd.org/D8689

Optimize telldir(3) Currently each call to telldir() requires a malloc and adds an entry to a linked list which must be traversed on future telldir(), seekdir(), closedir(), and readdir() calls. Applications that call telldir() for every directory entry incur O(n^2) behavior in readdir() and O(n) in telldir() and closedir(). This optimization eliminates the malloc() and linked list in most cases by packing the relevant information into a single long. On 64-bit architectures msdosfs, NFS, tmpfs, UFS, and ZFS can all use the packed representation. On 32-bit architectures msdosfs, NFS, and UFS can use the packed representation, but ZFS and tmpfs can only use it for about the first 128 files per directory. Memory savings is about 50 bytes per telldir(3) call. Speedup for telldir()-heavy directory traversals is about 20-30x for one million files per directory.

r320737: Fix cleanup in lib/libc/gen/setdomainname_test ATF cleanup routines run in separate processes from the tests themselves, so they can't share global variables. Also, setdomainname_test needs to be is_exclusive because the test cases access a global resource.

fnmatch(3): improve POSIX conformance. In a recent interpretation[1], "\\" shall return a non-zero value (indicating either no match or an error). The fix involves a change over r254091 and now the behavior matches the Sun/IBM/HP closed source implementations and also likely musl libc.
