Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

Mark MALLOC_DEFINEs static that have no corresponding MALLOC_DECLAREs.

This means that their use is restricted to a single C file.

- Fix races on detach handling of AAC_IFFLAGS_* mask
- Fix races on setting AAC_AIFFLAGS_ALLOCFIBS
- Remove some unused AAC_IFFLAGS_* bits.
Please note that the kthread still makes a difference between the
total mask and AAC_AIFFLAGS_ALLOCFIBS because more flags may be
added in the future to aifflags.

Revert part of r173264. Both aac_ioctl_sendfib and aac_ioctl_send_raw_srb

Revert part of r173264. Both aac_ioctl_sendfib and aac_ioctl_send_raw_srb
make use of the aac_ioctl_event callback, if aac_alloc_command fails. This
can end up in an infinite loop in the while loop in aac_release_command.

Further investigation into the issue mentioned by Scott Long [1] will be
necessary.

Previously, the aac driver did not handle enclosure management AIFs,
which were raised during hot-swap events. Now such events trigger cam
rescans, as is done in the mps driver.
