20. Allocate a single callout block on the stack at the start of pcre2_match()

and set its never-changing fields once only. Do the same for pcre2_dfa_match().

25. When PCRE2_FIRSTLINE without PCRE2_NO_START_OPTIMIZE was used in non-JIT
matching (both pcre2_match() and pcre2_dfa_match()) and the matched string
started with the first code unit of a newline sequence, matching failed because
the search for the first code unit stopped before rather than after the first
code unit of a newline in the subject string.
it was not tried at the newline.
26. Code for giving up a non-partial match after failing to find a starting
code unit anywhere in the subject was missing when searching for one of a
number of code units (the bitmap case) in both pcre2_match() and
pcre2_dfa_match(). This was a missing optimization rather than a bug.
27. Tidied up the ACROSSCHAR macro to be like FORWARDCHAR and BACKCHAR, using a
pointer argument rather than a code unit value. This should not have affected
the generated code.
