2107482334 scripts: move ProvidedSymbols() and SuggestBPP() to separate files 
ProvidedSymbols() used to be defined both in lib.prov.in and lib.req.in,
fix this code duplication by moving ProvidedSymbols() to separate
provided_symbols executable script.

Likewise, SuggestBPP() used to be defined both in lib.prov.in and
lib.req.in, fix this code duplication by moving SuggestBPP() to separate
suggest_bpp executable script.

4f4a1d1465 lib.prov, lib.req: enhance ProvidedSymbols 
This enhances ProvidedSymbols() in two ways:
* fixes st_shndx check for the case when it is not $7 in
"readelf --wide --dyn-syms" output as it happens on some architectures
like ppc64le;
* filters out special symbols (__bss_start, _edata, _end, _fini, _init)
after stripping of versioning.

3abcad0533 lib.req: do file-level dependencies for private libraries 
Private libraries are the ones which have non-standard prefix.
We choose to produce file-level dependency (without braces) on
such private libraries in two cases: 1) either the library was
found under RPM_BUILD_ROOT; or 2) no versioned symbols are used
from the library (no versioned references).

f0ec810739 factored lib.req and lib.prov 
Moved old code from find-requires and find-provides to lib.req and lib.prov.
For some reason, also a few python-related lines was removed.

Adapted lib.req and lib.prov to work without RPM_BUILD_ROOT.

In lib.prov, simplified RPM_FINDPROV_LIB_PATH handling (replaced
`lookup_path "$dir" "$PATH"' with `[ -z "${PATH##* $dir *}" ]').

Added lib.req.files and lib.prov.files.
