Add new entries:
- add support for PT_STEP, PT_GETREGS, PT_SETREGS, PT_GETFPREGS,
PT_SETFPREGS in all ports
- integrate all ptrace(2) features in gdb
- add ptrace(2) NetBSD support in LLDB

Before commited MP-safe patch, IPv4 test can run in time without
wait_for_disconnected. Currently, wait_for_disconnected is required
because of locking overhead.
CPU Debug Registers won't be exposed as is to userland.
Hardware Watchpoints will be exported to userland dedicated interface
through the ptrace(2) interface.

This feature was intended to detect stack overflow with CPU Debug Registers
(x86). It was never ported to other ports, neither amd64 and should be
adapted for SMP...
Currently there might be better ways to detect stack overflows like page
mapping protection. Since the number of Debug Registers is restricted
(4 on x86), torn it down completely.
This interface introduced helper functions for Debug Registers, they will
be replaced with the new <x86/dbregs.h> interface.
KSTACK_CHECK_DR0 was disabled by default and won't affect ordinary users.

This is more opaque and appropriate type, as vaddr_t is meant to be used
for vitual address value. Not all DR on x86 are used to represent virtual
address (DR6 and DR7 are definitely not).
No functional change intended.

output of ifconfig and if_baudrate was not good. Tested by nils@:
- The STATUS_TBIMODE bit in the STATUS register is deleted since 82575,
so check for 82575 and newer first and then check for old devices.
- Check the 2P5_SKU and 2P5_SKU_OVER bit for KX.
- Set IFM_2500_SX instead of IFM_1000_SX for 2.5G.
- Check SERDES's speed directly from the PCS layer (PCS_LSTS register) for old
devices.
- Style fix.
from nouveau code to drmfb. keep the same linebytes logic for i915.
nvidia hardware needs 256 byte alignment, so aligning to just 64 was
not enough.
fixes broken console with a width of 1440px (PR kern/51181)
ok riastradh
With this change this CH340 usb/serial based device:
https://www.olimex.com/Products/Breadboarding/BB-CH340T/open-source-hardware
(the chip is written H340T)
works as expected. As I'm not sure if this is needed for older device,
make this change for sc_version 0x30 or newer only.
While there, match USB_PRODUCT_WINCHIPHEAD2_CH341_2 too.
