Adds two gdb python scripts I've developed that may be useful to others:
drsymload: loads DR symbols regardless of gdb's current state,
which may include having DR symbols at the wrong address. It does
this by reading /proc/self/maps and running objdump on
libdynamorio.so. Ideally this would be integrated into a revived
libdynamorio.so-gdb.py: that's part of tools/libdynamorio.so-gdb.py causes "RuntimeError: Cannot access memory at address 0x712fd867" #2100.
memquery: prints the /proc/self/maps line for a given address.
I'm still shocked gdb doesn't provide such a command natively.
Issue: #2100
