./run: Adjust $PATH to include all libguestfs binaries.

Browse Source 
Instead of typing:

  ./run ./fish/guestfish ...

you can now use:

  ./run guestfish ...

This is shorter, but there are also two good reasons for this change:
It never made any sense to run the system-installed guestfish (or
other) binary.  It would be unlikely to work.  Also binaries in
libguestfs should be able to call other binaries freely without adding
special exceptions (which we had before this change).

@@ -278,34 +278,31 @@ You can run guestfish, guestmount and the virt tools without needing
to install, using the "./run" script in the top directory. This
script sets up some environment variables. For example:
./run ./fish/guestfish [usual guestfish args ...]
./run guestfish [usual guestfish args ...]
./run ./inspector/virt-inspector [usual virt-inspector args ...]
./run virt-inspector [usual virt-inspector args ...]
If you are already in the fish/ subdirectory, then the following
command will also work:
../run ./guestfish [...]
../run guestfish [...]
You can also make a link from your $PATH to the run script, eg:
cd ~/bin
ln -s ~/libguestfs/run libguestfs-run
cd ~/libguestfs
libguestfs-run ./inspector/virt-inspector [...]
The ./run script adds every libguestfs binary to the $PATH, so the
above example runs guestfish from the build directory (not the
globally installed guestfish if there is one).
You can also run the C programs under valgrind like this:
./run valgrind [valgrind opts...] ./cat/virt-cat [virt-cat opts...]
./run valgrind [valgrind opts...] virt-cat [virt-cat opts...]
or under gdb:
./run gdb --args ./cat/virt-cat [virt-cat opts...]
./run gdb --args virt-cat [virt-cat opts...]
This also works with sudo (eg. if you need root access for libvirt or
to access a block device):
sudo ./run ./cat/virt-cat -d LinuxGuest /etc/passwd
sudo ./run virt-cat -d LinuxGuest /etc/passwd
