Be consistent with the naming of the variable used to store the
...
function return value. Previously, some code used "rval", some
used "ret". This standardizes on "ret" and uses "rc" for temporary
return codes.

We require ANSI C so stop using the obsolete STDC_HEADERS.

Don't use dlsym() to find the libc getenv() since this may allocate
...
memory on some systems (glibc) which leads to a hang if malloc()
calls getenv() (jemalloc).

Mark the putenv(), setenv() and unsetenv() symbols as global, not
...
hidden. Fixes a mismatch where a plugin (or its loaded dso) would
call setenv() to set a variables but be unable to find it later
with getenv().

Add wrapper functions for dlopen() et al so that we can support
...
statically compiling in the sudoers plugin but still allow other
plugins to be loaded. The new --enable-static-sudoers configure
option will cause the sudoers plugin to be compiled statically into
the sudo binary. This does not prevent other plugins from being
loaded as per sudo.conf.

Initial cut at a hooks implementation. The plugin can register
...
hooks for getenv, putenv, setenv and unsetenv. This makes it
possible for the plugin to trap changes to the environment made by
authentication methods such as PAM or BSD auth so that such changes
are reflected in the environment passed back to sudo for execve().
