cb810c48c0 patch: fix matching failure 
Fix matching failure when plist is advanced while checking for buffered
lines - the lines in the hunk that are about to be added should be
skipped when checking for matching context.

Also add a valid test case that fails with current busybox and is fixed
by the change.

If we reach the end of plist it means the input has still data while we
are expecting EOF. Fix the log to avoid a crash.

9d113cac42 patch: tweaks 
1) Eliminate spurious warnings about possibly reduced hunks.  Instead only
note a possible location if we don't find a non-reversed place to apply it.
(Otherwise, hunks that move code forward around within a file look reversed at
the removal site.)

2) Open the source file read-only, so we can apply patches to read-only files.
