In order to work as if it were already adopted by upstream
gnulib, put bootstrap and supporting scripts into the local
gnulib overrides directory.
* bootstrap, build-aux/extract-trace, build-aux/funclib.sh,
build-aux/inline-source, build-aux/options-parser: Move from
here...
* gl/build-aux/bootstrap.in, gl/build-aux/extract-trace,
gl/build-aux/funclib.sh, gl/build-aux/inline-source,
gl/build-aux/options-parser: ...to here.
* gl/build-aux/options-parser (func_version): Show only the
first copyright notice on files generated with inline-source.
* gl/doc/bootstrap.texi: Developer documentation for bootstrap.
* gl/modules/extract-trace, gl/modules/funclib.sh,
gl/modules/inline-source, gl/modules/options-parser: Describe
dependencies for gnulib-tool.
* bootstrap.conf (gnulib_modules): Add extract-trace,
inline-source and options-parser modules.
* bootstrap: Regenerated from gnulib overrides as a mono-
lithic script file using gl/build-aux/inline-source.
