Subject: [PATCH] core: Remove MES_PKGDATADIR.

* configure: Do not add MES_PKGDATADIR to config.h.
* configure.sh: Likewise.
* simple.sh: Likewise.
* src/mes.c (open_boot): Do not use MES_PKGDATADIR; rely on
MES_PREFIX or cwd.

    core: Throw instead of segfault on non-existing input file.  WIP.
    
    Reported by theruran.
    
    * src/posix.c (open_input_file): Call error instead of failing silently.
