scripts/gdb: add lx-symbols command
This is probably the most useful helper when debugging kernel modules: lx-symbols first reloads vmlinux. Then it searches recursively for *.ko files in the specified paths and the current directory. Finally it walks the kernel's module list, issuing the necessary add-symbol-file command for each loaded module so that gdb knows which module symbol corresponds to which address. It also looks up variable sections (bss, data, rodata) and appends their address to the add-symbole-file command line. This allows to access global module variables just like any other variable.
