The existing implementation had a broken comparison that could overflow.
Replace this with a check that avoids the overflow before it happens.
Consistently return a maximum value also on the case of negative
arguments since negative is considered an overflow and means
infinity for our current setrlimit().

from r202992. The refcount on the cache entry is not initialized, so
any attempt to clean the cache will skip over this item since it likely
has a >0 value.
This change is currently a NOP. There is work in progress to support
freeing the cache which requires this change to avoid a memory leak.

This brings support for multi-threaded compression. This brings close
N times faster compression where N is the number of CPU cores.
Because of this, liblzma now depends on libthr.
Soon libarchive will be modified to use the new lzma API.
Thanks to antoine@ for the exp-run.

In a couple of cases a variable "stayopen" can be checked
unitialized. This is of no danger as the complementary

allows the user to request administrative changes to individual devices
such as attach or detaching drivers or disabling and re-enabling devices.
- Add a new /dev/devctl2 character device which uses ioctls for device
requests. The ioctls use a common 'struct devreq' which is somewhat
similar to 'struct ifreq'.
- The ioctls identify the device to operate on via a string. This
string can either by the device's name, or it can be a bus-specific
address. (For unattached devices, a bus address is the only way to
locate a device.) Bus drivers register an eventhandler to claim
unrecognized device names that the driver recognizes as a valid address.
Two buses currently support addresses: ACPI recognizes any device
in the ACPI namespace via its full path starting with "\" and
the PCI bus driver recognizes an address specification of
'pci[<domain>:]<bus>:<slot>:<func>' (identical to the PCI selector
strings supported by pciconf).
- To make it easier to cut and paste, change the PnP location string
in the PCI bus driver to output a full PCI selector string rather
than 'slot=<slot> function=<func>'.
- Add a devctl(3) interface in libdevctl which provides a wrapper around
the ioctls and is the preferred interface for other userland code.
- Add a devctl(8) program which is a simple wrapper around the requests
supported by devctl(3).
- Add a device_is_suspended() function to check DF_SUSPENDED.
- Add a resource_unset_value() function that can be used to remove a
hint from the kernel environment. This is used to clear a
hint.<driver>.<unit>.disabled hint when re-enabling a boot-time
disabled device.

This was a local addition to the original change from NetBSD.
Being this libc there is some chance for it to interfere with
user's cget*() functions usage. The memory leak was finely
plugged by r278300.

It seems GAS makes the substitution automatically, but Clang's
