* MFC r309650:ed2016-12-202-2/+9
| | | | | | | | | Properly sign extend the result of jrand48() and mrand48(). These functions are supposed to return a value between [-2^31, 2^31). This doesn't seem to work on 64-bit systems, where we return a value between [0, 3^32). Patch up the function to use proper casts to int32_t. While there, fix some other style bugs.

| | | | | | Fix libusb20_dev_get_desc(3) to use the "vendor product" order, not "product vendor". This is consistent with how it's generally done. The ordering is visible eg in usbconfig(8) output.

| | | | | | | | | | Speed up pw operations that edit /etc/group or /etc/passwd r285050 fixed a bug in pw that could lead to /etc/passwd or /etc/group corruption on power loss. However, it fixed it by opening those files with O_SYNC, which is very slow, especially on ZFS. This change replaces O_SYNC with appropriately placed fsync()s instead, which is much faster. Using a ZFS tmpdir, the time to run pw's kyua tests drops from 245s to 35s.

| | | | | | | | | | | | | Export the whole thread name in kinfo_proc kinfo_proc::ki_tdname is three characters shorter than thread::td_name. Add a ki_moretdname field for these three extra characters. Add the new field to kinfo_proc32, as well. Update all in-tree consumers to read the new field and assemble the full name, except for lldb's HostThreadFreeBSD.cpp, which I will handle separately. Bump __FreeBSD_version. Sponsored by: Dell EMC

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix error reporting from wcstof() When wcstof() skipped initial space and then parsing failed, it set endptr to the first non-space character. Fix it to correctly report failure by setting endptr to the beginning of the input string. The fix is from theraven@, who fixed this bug in wcstod() and wcstold() in r227753. While I'm here: Move assignments out of declarations in wcstod() and wcstold(). This is against my personal preference, but it is our agreed style(9). Set endptr correctly on malloc() failure in all three functions. Remove an incorrect comment: This is pointer arithmetic, so the code was not actually making that assumption. wcstold() advanced the wcp pointer beyond leading whitespace and then reset it back to the beginning of the string. Do not reset it. This seems to have no functional effect, since strtold_l() also skips leading whitespace. I'm making the change to keep this function consistent with wcstof() and wcstod(), and because the C11 spec prescribes the use of iswspace() to skip leading space.

| | | | | | | | | | | Add a new 'clear driver' command for devctl along with the accompanying ioctl and devctl_clear_driver() library routine to reset a device to use a wildcard devclass instead of a fixed devclass. This can be used to undo a previous 'set driver' command. After the device's name has been reset to permit wildcard names, it is reprobed so that it can attach to newly-available (to it) device drivers. Sponsored by: Chelsio Communications

Requested by: jmmv r305170: Don't bake all of CC/CPP/CXX into CFLAGS Capture executable names for CC, CPP, CXX (assumed to be the first non-CCACHE_BIN word). This change strips out all of the cross-compiler arguments, (-target, -B, etc), added to ${CC}, etc via ${CROSSENV} in Makefile.inc1, so it doesn't infect the build and subsequently the test. Add comments noting why this logic is being added, and why the logic in r305041 was necessary/what it was trying to achieve. This is required after recent changes made to the toolchain to always specify --sysroot, -target, -B, etc with clang in buildworld (presumably r304681).
