Finish cleanup in kvm.c revisions 1.10 and 1.11 -- mark sf (swapfile)
argument to kvm_open() and kvm_openfiles() as unused.

BSD didn't read swap since kvm.c CSRG revision 5.21 (u-area is pageable
under new VM. no need to read from swap.)

The old !NEWVM code was removed in CSRG revision 5.23 (~ten years ago).

Compensate for "Compensate for header dethreading" by backing it out.

Implement __FBSDID()

Compensate for header dethreading.

Limit the amount of data copied to the error buffer to _POSIX2_LINE_MAX.
This is the documented size which the user-provided buffer must be.

Change the return value of kvm_read/kvm_write to be -1 on error, to
match the documented interface.

Previously it returned 0 on error.

Use kldsym(2) to lookup symbol values. This avoids the kvm_mkdb juggling
and is module aware. Yes, this means that kvm_nlist(3) will find symbols
in loaded modules. The emulation of the nlist struct is pretty crude but
seems to work well enough for all the users in the tree that I found.

Don't open the swap file. The open descriptor for it hasn't been used
for over 5 years since we switched to using procfs for kvm_uread().
This cleanup was motivated by recent breakage of the default swap file
(/dev/drum) when swapon() has not been called.

phkmalloc strikes again! :-) Another use of un-cleared returns from

Remove trailing whitespace.

Fix previous fix to agree with the man page - don't report errors in
kvm_open() if errstr is NULL.

Remove some unused variables and fix two blatant core dump triggers.
