This makes discovery of the Module.symvers happen at model build time,
instead of at build tree creation/configuration.

A find_module_symvers script is included to find the Module.symvers
file, and it's used in the RCG Makefile to find module symvers files
at build time.

This reverts the top-level configure script changes from
8c01de98, restoring the configure
script and dropping the autoconf-generated configure step from the
build setup.

Closes #14 - Restore support for kernel module versioning
patches/kernel-4.19-cs/config-4.19.67-cs - change to MODVERSIONS=y
patches/kernel-4.19-cs/README - Update note on config file
-- changes for mbuf, gpstime symbol versions --
Update RCG autotools - remove configure, move configure.in to configure.ac
bootstrap - add to generate configure from configure.ac
configure.ac - rename from configure.in, add tests to find path to mbuf, gpstime
Module.symvers files - either /var/lib/dkms/$MODNAME/$MODVERS/$KVERS/$ARCH/
for DKMS package or /var/cache/$MODNAME from local build
src/drv/ExtraSymbols.symvers - Remove mbuf, gpstime symbols
src/drv/gpstime/Makefile - Add caching of Module.symvers in /var/cache/gpstime on install
src/drv/mbuf/Makefile - Add caching of Module.symvers in /var/cache/mbuf on install
src/epics/util/Makefile.in  - Add mbuf,gpstime Module.symvers paths
src/epics/util/feCodeGen.pl - Add KBUILD_EXTRA_SYMBOLS statements to front-end make file
-- changes to front-end kernel module symbol versions --
src/drv/ExtraSymbols.symvers - Remove need_to_load_IOP_first
src/epics/util/Makefile.in - Add caching of need_to_load_IOP_first symbol version, copy of cache for builds
src/epics/util/feCodeGen.pl - Add KBUILD_EXTRA_SYMBOLS for this
