Normalize include guards in gdb

While working on my other scripts to deal with gdb headers, I noticed that some files were missing include guards. I wrote a script to add the missing ones, but found that using the obvious names for the guards ran into clashes -- for example, gdb/nat/linux-nat.h used "LINUX_NAT_H", but this was also the script's choice for gdb/linux-nat.h. So, I changed the script to normalize all include guards in gdb. This patch is the result. As usual the script is available here: https://github.com/tromey/gdb-refactoring-scripts Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the buildbot. gdb/ChangeLog 2019-02-07 Tom
