Move the DDB-specific part of vpanic() to a new db_panic() function, defined in ddb/db_panic.c and declared in ddb/ddbvar.h. No functional change. The copyright years in db_panic.c are the years in which changes were made to the code that has now been moved to db_panic.c. No pre-NetBSD copyright notice is needed because revision 1.12 of subr_prf.c had only the trivial "#ifdef DDB \\ Debugger(); \\ #endif"

Add options DDB_FROMCONSOLE and sysctl ddb.fromconsole, analagous to DDB_ONPANIC. Lets user ignore breaks but enter DDB on panic. Intended for machines where debug on panic is useful, but DDB entry is not, (public-access console, or terminal-servers which send spurious breaks) Add new ddb hook, console_debugger(), which decides whether or not to ignore console ddb requests. Console drivers should be updated to call console_debugger(), not Debugger(), in response to serial-console break or ddb keyboard sequence.

extern int db_fromconsole;
Implement ddb setting that allows all ddb output to be teed into the kernel message buffer/log. Its off by default and can be switched on in the kernel configuration on build time, be set as a variable in ddb and be set using sysctl. This adds the sysctl value ddb.tee_msgbuf = 0 by default. The functionality is especially added and aimed for developers who are not blessed with a serial console and wish to keep all their ddb output in the log. Specifying /l as a modifier to some selected commands will also put the output in the log but not all commands provide one nor has the same meaning for all commands. This feature could in the future also be implemented as an ddb command but that could lead to more bloat allthough maybe easier for non developpers to use when mailing their backtraces from kernel crashes.
