Revert the changes that827f25fmade to libc/calls/readv-metal.c regarding internal functions having underlines due to6f7d0cbbeing missing at the time. Use the versions of libc/intrin/lockfileex.c and libc/intrin/unlockfileex.c from3f49889to account for strace changes. Revertd86916eand use the versions of libc/calls/getgroups.c, libc/calls/setgroups.c, libc/runtime/getlogin.c and libc/runtime/getlogin_r.c from4c40c50to again account for strace changes. Fix include statements and internal underlined function calls in libc/stdio/cocmd.c, libc/testlib/extract.c and test/libc/stdio/system_test.c. Fix missing closing paren in nsync memory size macro in memtrack.internal.h.
