fix multiplei repetitive typos in comments, messages and documentation. mainly because copy paste code big amount of files are affected.

Add missing __KERNEL_RCSID().

Add NetBSD RCS IDs. No functional change.

Fix checking return value of atomic_cas_uint().

This change fixes a bug that extra delay() is called only once even if
atomic_cas_uint() isn't failed or delay() isn't called when atomic_cas_uint()
failed.

The reason of this bug was that I simply converted FreeBSD' atomic_cmpset_int()
to atomic_cas_uint(). The return value's semantics is different.

No functional change:

- Remove unused code.
- Remove extra spaces.
- KNF.

Sync with the remaining part of FreeBSD r328265 except sfp_reinit stuff:
- Always schedule module intterrupt in ixgbe_config_link() when a device is
SFP+ based.
- Use not loop index but txr->me

Sync with the remaining part of FreeBSD r328265 except sfp_reinit stuff:
- Always schedule module intterrupt in ixgbe_config_link() when a device is
SFP+ based.
- Use not loop index but txr->me in ixv_initialize_{transmit,receive}_units().
It's required for VMDQ but NetBSD doesn't use it, so it's not a bug in
NetBSD.
- Simplify ixgbe_bp_wd_set(). No functional change.
- Whitespace.

Add some changes from ix-3.2.17.tar.gz and r328265. Not fully synchronized.
Some others (e.g. sfp cage interrupt and bypass adapter stuff) will be merged

Add some changes from ix-3.2.17.tar.gz and r328265. Not fully synchronized.
Some others (e.g. sfp cage interrupt and bypass adapter stuff) will be merged
later:
- Initialize firmware command buffer correctly in ixgbe_read_ee_hostif_X550()
and ixgbe_read_ee_hostif_buffer_X550(). These functions are used when reading
NVM.
- Fix a bug that ixgbe_mng_present() misunderstand management capability on
X550 and newer on some environment. X550 changed FWSM bit definition.
See X540 document and X550's document and compare them.
- Fix checksum calculation in ixgbe_set_fw_drv_ver_generic(). This function is
not used in NetBSD.
- Add some unused funtions.
- Whitespace fix.

Fix a bug that bypass adapter's sysctls aren't set. Tested with non-genuine
X550-T2 bypass adapter:
- Call ixgbe_sysctl_instance() in ixgbe_bypass_init() to get sysctl's top node
correctly.
- ixgbe_init_device_features() refers adapter->hw.bus.func for bypass adapter.
Call set_lan_id() to set adapter->hw.bus.func before calling
ixgbe_init_device_features(). Without this, bypass sysctl's are added to
both the first and second port.
- Initalize node.sysctl_data before calling sysctl_lookup() to read correct
value.
