Merge branch 'ab/pickaxe-pcre2'
Rewrite the backend for "diff -G/-S" to use pcre2 engine when

xdiff-interface: replace discard_hunk_line() with a flag
xdiff users: use designated initializers for out_line
pickaxe -G: don't special-case create/delete
pickaxe -G: terminate early on matching lines
xdiff-interface: allow early return from xdiff_emit_line_fn
xdiff-interface: prepare for allowing early return
pickaxe -S: slightly optimize contains()
pickaxe: rename variables in has_changes() for brevity
pickaxe -S: support content with NULs under --pickaxe-regex
pickaxe: assert that we must have a needle under -G or -S
pickaxe: refactor function selection in diffcore-pickaxe()
perf: add performance test for pickaxe
pickaxe/style: consolidate declarations and assignments
diff.h: move pickaxe fields together again
pickaxe: die when --find-object and --pickaxe-all are combined
pickaxe: die when -G and --pickaxe-regex are combined
pickaxe tests: add missing test for --no-pickaxe-regex being an error
pickaxe tests: test for -G, -S and --find-object incompatibility
pickaxe tests: add test for "log -S" not being a regex
pickaxe tests: add test for diffgrep_consume() internals
