(even if built --with-webdav-props --with-webdav-locks)

This permits building mod_webdav.so and an alternative mod_webdav_min.so
without the extra dependencies if the build system is extended to build
mod_webdav_min, compiling mod_webdav.c with -DMOD_WEBDAV_BUILD_MINIMAL
-Dmod_webdav_plugin_init=mod_webdav_min_plugin_init
(note: build systems have not been extended here for mod_webdav_min.so)

[core] manually calculate off_t max (fixes #3171)

manually calculate off_t max for broken cross-compilation systems which
fail to enable large file support (so sizeof(off_t) != sizeof(int64_t))

If sizeof(off_t) != sizeof(int64_t), a negative number could end up in
cq->upload_temp_file_size when it was assigned INTMAX_MAX, leading to
excessive new temporary file creation occurring on each and every write.

[mod_webdav] alt handling PROPFIND on collection

alternative way of handling PROPFIND on collection where the request was
made without a trailing slash. Instead of sending 308 redirect in some
cases, set Content-Location response header *and* treat as if request
had been made with trailing slash on the collection for PROPFIND and
PROPPATCH.

https://www.rfc-editor.org/rfc/rfc4918#section-5.2
There is a standing convention that when a collection is referred to
by its name without a trailing slash, the server MAY handle the
request as if the trailing slash were present. In this case, it
SHOULD return a Content-Location header in the response, pointing to
the URL ending with the "/".

[mod_webdav] If-None-Match: * on non-existent

fix logic for If-None-Match: * test on non-existent entity
(regression in lighttpd 1.4.64)

If-None-Match: * should not fail on a non-existent entity,
as it may be used to make the request conditional on the
origin server having no current representation of the entity.
(see If-None-Match in RFC2616 and RFC7232)

(This logic had been changed in lighttpd 1.4.64 in
commit 8a535e7e064b0c33c3b60a92df88b349d79b94c2
when allowing bogus, non-'*' If-None-Match etags
for non-existent entities to not-match (and pass the check)

[multiple] shared code for struct chunk and mmap

chunkqueue_chunk_file_view()

reduces size of struct chunk

use mmap with mod_deflate libdeflate, if mmap available,
even when lighttpd not built with --enable-mmap

avoid using mmap on temp files in chunkqueue (c->file.is_temp)
since pread() with a reasonable block size is typically as fast
or faster than mmap on files read sequentially and used only once,
especially when writing results to limited-size socket buffers
(and lighttpd temp files are, in most cases, by default about 1 MB)
(Exception: sometimes mmap is used for convenience or to fulfill
a requirement, e.g. one-shot libdeflate in mod_deflate)
(There are many factors which influence speed of mmap versus pread,
so this should not be construed as generic usage advice.)

There is no COPYFILE_CLONE_FORCE on OSX <10.12 so fall back to using

using copyfile() with flags equivalent to COPYFILE_CLONE_FORCE, but

[mod_webdav] copy acceleration

* copy acceleration
* safety for accelerated copying of files > 2 GB on 32-bit systems
* disable hard linking when "deprecated-unsafe-partial-put" => "enable"
(In normal operation, hard-linking is safe for copying since WebDAV
modification of any file involves full upload of file and atomic
replacement, which severs any hard-links. When deprecated unsafe
partial PUT is permitted, that is not the case.)
