Re #320.
We have seen this from buggy backends that present NULL for constraint
string_lists. This is probably illegal behaviour from backends but we
don't want to crash.
h5400 now checks validity of -l, -t, -x and -y and auto selects a supported resolution.
scanimage now shows the full range for -x and -y despite other selections.
This creates temporary strings that correspond to the colon-delimited
username and password that are read from file in `auth_callback()`.
The null-terminated strings are used directly to determine lengths.
The AX_CXX_COMPILE_STDCXX* macros that were embedded in aclocal.m4
have been replaced with the versions found in the autoconf-archive
package from Debian 9.
Flags like -a, -d and -s have many overlap effects. This patch restricts
the effect of flags to a simple action.
New -u (user) flag replaces -a optional argument for running saned as a different user.
The code that retrieve the user info and drop privileges migrated to runas_user().
As a side effect, PID file can be created even if getting user info fails.
New -l (listen) flag sets run_mode to standalone.
New -D (daemonize) flag daemonizes saned after bind.
New -o (once) make saned exit after the first client disconnects.
Flag -s (syslog) is gone. Previous behavior can be reproduced with '-a -d level -o -f'.
New -e (stderr) flag for redirecting output to stderr, instead of syslog.
Flag -d (debug) now only sets the debug level and argument is required. Previous behavior
can be reproduced with '-a -d level -o -f -e'.
The run_mode SANED_RUN_DEBUG and SANED_RUN_ALONE shared most of its code
path. With the new flags dealing with their difference, SANED_RUN_DEBUG is gone.
Flag '-a' still works as before but it can be replaced by '-l -D -u user'.
Current uses of -d (debug) or -s (syslog) will break.

The fileno() is only available if its feature test macro passes. The
various symbols are defined appropriately in ../include/sane/config.h
during configuration of the build.
