when allocating the record in the first place, allocate the final buffer
when closing the BSM record. At that point, more size information is
available, so a sufficiently large buffer can be allocated.
This allows the kernel to generate audit records in excess of
MAXAUDITDATA bytes, but is consistent with Solaris's behavior. This only
comes up when auditing command line arguments, in which case we presume
the administrator really does want the data as they have specified the
policy flag to gather them.

Add the argument auditing functions for argv and env.
Add kernel-specific versions of the tokenizer functions for the
arg and env represented as a char array.
Implement the AUDIT_ARGV and AUDIT_ARGE audit policy commands to
enable/disable argv/env auditing.
Call the argument auditing from the exec system calls.

token. This change covers the pid < 0 cases, and pid lookup
failure cases.

- Clarify and clean up AUR_ types to match Solaris.
- Clean up use of host vs. network byte order for IP addresses.
- Remove combined user/kernel implementations of some token creation
calls, such as au_to_file(), header calls, etc.

an incompatible conversion from a 64-bit pointer to a 32-bit integer on
64-bit platforms. We will investigate whether Solaris uses a 64-bit
token here, or a new record here, in order to avoid truncating user
pointers that are 64-bit. However, in the mean time, truncation is fine
as these are rarely/never used fields in audit records.
