Allow for module-path being a semicolon-separated list of dirs. This is consistent with kern.module_path sysctl and also compensates for the unconventional syntax of asf(8) where the last of multiple arguments is the output file, which prevents us from using the traditional Unix syntax "foo file ..." to specify multiple module dirs.

.Nm
Give a major overhaul to asf(8). The improvements are: - can get the kld info from core files via kvm(3); - can use kldstat(2) directly, which is a piece of cake; - can use .symbols or whatever, which allows for use by non-developers when reporting system crashes -- now asf(8) can be mentioned in the handbook at last; - speed (no more double fts(3) per loaded module); - various bugs fixed. At the same time, the new asf(8) should stay compatible with the old one, bar bugs. Perhaps some defaults may be changed later to match today's state of affairs.

append to the file rather than overwriting it.
Add a "-f" flag for asf(8) which performs a search to find the each module no matter where in the directory structure it may be. Use this and the "-k" flag in the generated gdbinit files so that the "getsyms" function in gdb requires no user intervention to run and will find every module if they're in the kernel build's module directory. This is still quite useful for cases where gdb knows that the path for some modules is /boot/kernel and others are in the object directory for /usr/src/sys/$ARCH/compile/kernel. Approved by: grog
