[Rpm-maint] [rpm-software-management/rpm] Use file path in %patch macro (#629)

[Petr Menšík]

Hi. This is my test approach to allow redefinition of patch application in old plain spec files. All references with 
```
%patch1 -p1
%patch2 -p1
```
etc. cannot be redefined. There is quite nice %apply_patch macro and %autopatch, which allows applying all patches in automated way. Unfortunately, it is not always so simple. One try to solve that is request #626. This is another improvement, but with more complicated solution. It moves %patchX handling from rpmbuild to macro definitions. It is then possible to apply patches with SCM method.

```
# Switch to scm method. Pass file name and file number to patch as arguments.
%__apply_patchx_plain(b:d:o:F:REp:m:)\
%{apply_patch %{-p} -m "%{1}" %{1} %{2}}
%__apply_patchx_uncompress(b:d:o:F:REp:m:)\
%{apply_patch %{-p} -m "%{1}" %{1} %{2}}
```

This allows rebase tool to mark each commit, by patch name it comes from and patch number. It could allow creation of git repository, where commits could be marked with original file. After git driven rebase, all patches could be exported back to patches used by spec, in automated way. Currently, it is impossible, because patch number is dropped in rpmbuild.
