Prior to this change, the assumption in all shell and Python scripts was
that the Bash interpreter would always be available at `/bin/bash`, and
Python would always be available at `/usr/bin/python`. However, on a VM
running FreeBSD, installing bash and python using the pkg command
installs them under /usr/local/bin.
This change updates the paths to use /usr/bin/env in the shebang. While
this is not a standard path either, it is more likely to be available at
this location.
This change also updates the find command in common_infra.sh to use
`-perm -+x` in lieu of `-executable`, which is not a condition defined
by POSIX. This allows running the tests on BSD.
This change adds additional compiler warnings as detected by the
autoconf archive. Because the code is susceptible to these additional
warnings, disable treating warnings as errors for now, until we can fix
the warnings.
This disables the include file list and dependency graph in the file
view. In addition, the groups are updated to include `libx52` in their
names, to avoid any potential conflict.
