The "apply" DSL method can be called from patch-do blocks to specify
the paths within an archive of the desired patch files, which will be
applied in the order in which they were supplied to the "apply" calls.
If "apply" isn't used, raise an error whenever the extracted directory
doesn't contain exactly one file.
The "apply" method can be called zero or more times within a patch-do
block with the following syntaxes supported:
apply "single_apply"
apply "multiple_apply_1", "multiple_apply_2"
apply [array_of_apply]
If apply must be used, a single call using the second syntax above is
usually best practice. Each apply leaf should be the relative path to a
specific patch file in the extracted directory.
For example, if extracting this-v123-patches.tar.gz gives you
this-123
this-123/.DS_Store
this-123/LICENSE.txt
this-123/patches
this-123/patches/A.diff
this-123/patches/B.diff
this-123/patches/C.diff
this-123/README.txt
and you want to apply only B.diff and C.diff, then you need to use
"patches/B.diff" and "patches/C.diff" for the lowest-level apply leaves.

- remove support for IO objects, since we no longer access ::DATA
directly
- since we don't need to support IO objects, use a separate class for
string patches and stop wrapping strings in StringIO ojects
This commit introduces a new patch implementation that supports
checksums and caching.
Patches are declared in blocks:
patch do
url ...
sha1 ...
end
A strip level of -p1 is assumed. It can be overridden using a symbol
argument:
patch :p0 do
url ...
sha1 ...
end
Patches can be declared in stable, devel, and head blocks. This form is
preferred over using conditionals.
stable do
# ...
patch do
url ...
sha1 ...
end
end
Embedded (__END__) patches are declared like so:
patch :DATA
patch :p0, :DATA
Patches can also be embedded by passing a string. This makes it possible
to provide multiple embedded patches while making only some of them
conditional.
patch :p0, "..."
