Winfried Plappert 5148608c39 restic rewrite include - based on restic 0.18.1
cmd/restic/cmd_rewrite.go:
introduction of include filters for this command:
- add include filters, add error checking code
- add new parameter 'keepEmptyDirectoryFunc' to 'walker.NewSnapshotSizeRewriter()',
  so empty directories have to be kept to keep the directory structure intact
- add parameter 'keepEmptySnapshot' to 'filterAndReplaceSnapshot()' to keep snapshots
  intact when nothing is to be included
- introduce helper function 'gatherIncludeFilters()' and 'gatherExcludeFilters()' to
  keep code flow clean

cmd/restic/cmd_rewrite_integration_test.go:
add several new tests around the 'include' functionality

internal/filter/include.go:
this is where is include filter is defined

internal/walker/rewriter.go:
- struct RewriteOpts gains field 'KeepEmtpyDirectory', which is a 'NodeKeepEmptyDirectoryFunc()'
  which defaults to nil, so that al subdirectories are kept
- function 'NewSnapshotSizeRewriter()' gains the parameter 'keepEmptyDirecoryFilter' which
  controls the management of empty subdirectories in case of include filters active

internal/data/tree.go:
gains a function Count() for checking the number if node elements in a newly built tree

internal/walker/rewriter_test.go:
function 'NewSnapshotSizeRewriter()' gets an additional parameter nil to keeps things happy

cmd/restic/cmd_repair_snapshots.go:
function 'filterAndReplaceSnapshot()' gets an additional parameter 'keepEmptySnapshot=nil'
