The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

bsdiff: fix off-by-one error2020-11-16T18:41:49ZMitchell Hornemhorne@FreeBSD.org2020-11-16T18:41:49Zurn:sha1:a521f2116473fbd8c09db395518f060a27d02334
The program reads oldsize bytes from oldfile, and proceeds to initialize
a suffix array of oldsize elements using divsufsort(). As per the
function's API [1], array indices 0 through n-1 are initialized.
Later, search() is called, but with index bounds [0, n]. Depending on
the contents of the malloc'd buffer, accessing this uninitialized index
at the end of can result in a segmentation fault. Fix this by passing
oldsize-1 to search(), limiting the search bounds to [0, n-1].
This bug is a result of r303285, which introduced divsufsort() as an
alternate suffix sorting function to the existing qsufsort(). It seems
that qsufsort() did initialize the final empty element, meaning it could
be safely accessed. This difference in the implementations was missed at
the time.

bspatch: add integer overflow checks2019-09-26T13:27:25ZEd Masteemaste@FreeBSD.org2019-09-26T13:27:25Zurn:sha1:20bd59416dcacbd2b776fe49dfa193900f303287
Introduce a new add_off_t static function that exits with an error
message if there's an overflow, otherwise returns their sum. Use this
when adding values obtained from the input patch.
