This patch adds two GNU extensions to awk. In essence, it allows -f to
be mixed with programs defined on the command line, with or without -e.
I know this is breaks POSIX and is a GNU extension, but it is really
convenient, especially when you want to organize awk functions into
libraries. Thus, it is controlled by FEATURE_AWK_GNU_EXTENSIONS.

Add the extension -e to awk.
Add the ability to mix -f and command line program definitions.
This enables the use of awk library files that are pulled in
with -f, while the "main" program is defined on the command line.
Example: awk -f mylib.awk '{print myfunction($1);}' ...
With FEATURE_AWK_GNU_EXTENSIONS:
function old new delta
awk_main 1054 1127 +73
.rodata 149787 149799 +12
packed_usage 29128 29135 +7
