Improve multi-line kernel ident parsing

Instead of blindly grabbing the line with 'Version string' and the
following one from the core info file, take all lines after 'Version
string' until the one one that matches the field format in the core info
file. This provides compatibility with VendorBSD modifications that have
a different kernel ident format.

Teach crashinfo(8) to look at the currently running kernel (based on the
kern.bootfile sysctl). Prior to this commit, crashinfo(8) only looks at
/boot/*/kernel; this includes the usual places where kernels reside, so
for most systems this will have no effect.

Set umask to 0x077 instead of the default. This prevents non-root user
from reading crashinfo output, which could contain some sensitive
information.

Add a script to perform simple analysis of a crash dump (either a full
dump or minidump). When the script is run, it generates a text file
containing the output of several commands run againt the core dump such
as kgdb (stack trace), ps, netstat, vmstat, iostat, dmesg, and fstat.
