global: Use buffer_get_writable_size() where possible
With 09539f3db increasing buffer's init_size with +1 some fts-icu unit tests
started failing. And in general it's better to use the writable size since
that provides the true size that can be used.

quota: Optimize handling a large number of expunges.
This assumes that the mail_expunge() was called in the same order as
sync_notify(), which practically means that they were both done in
ascending uid order. This is usually true.

lib-index: Use a bit larger initial records buffer size
For example with a mailbox having 160k messages the buffer size is around
10MB. Adding just 1% more space to it allows a lot more appends before the
buffer needs to be realloced. This reduces CPU usage quite a lot.

lib: Use p_malloc() explicitly in first buffer_alloc()

lib-mail: More fixes to istream-header-filter with large input.
Don't assume that when reading the header the second time we'll get exactly
the same header blocks as the first time.
This commit also prevents the filter callback from switching the
matching-decision on non-first header line. This shouldn't be needed and it
could just cause confusion. (It also made it a bit easier to implement this
fix.)

Existing code already assumes that the callback is called for all the header

lib-storage: Don't use same session ID for multiple mail_storage_service_next() calls.
dsync does multiple mail_storage_service_next() calls for the same

session ID to stats process, which complains about duplicates. Solved this
in a generic way by having the following mail_storage_service_next() calls

imapc: Fixed crash caused by pool_unref() API change.
Calling pool_unref() set the mail_private->pool=NULL, which crashed in

existing FETCHes to finish, so the callback will always have only
valid mails with valid pools.

Split parts of lib-dict into lib-dict-extra.
Otherwise there's a circular dependency because lib-dict/dict-fs.c depends
on lib-fs, while lib-fs/fs-dict.c depends on lib-dict. This becomes a problem
when compiling --without-shared-libs, although for some reason it works for
me while linking the Dovecot core, but not when linking external plugins.
If inner MIME part had the same --boundary prefix as its parent(s) and
the MIME part body started with the inner --boundary prefix, we didn't yet
have it in the list of valid boundaries, so we thought that the outer
boundary was found and the MIME headers were truncated. But due to an extra
bug we still treated it as if it were the inner boundary, except the MIME
part sizes/offsets were set wrong.
This for example fixes a situation where FETCH [1.2.MIME] returns an extra
newline before the actual headers.

A hardcoded value of 100 isn't necessarily enough if there are a lot of

Probably smaller number would be fine too.

If the remote server supports CONDSTORE or QRESYNC extensions we'll use the

correctly on an open mailbox, so this feature shouldn't be fully relied on.
It was primarily implemented for dsync+imapc support - both for preserving
modseqs and also for HIGHESTMODSEQ lookups.

lib-http: client: Implemented means to set request payload buffer rather than an input stream.
This is not purely a convenience function: there have been bugs caused by allocating a data input stream from a datastack buffer.
With this function, the buffer is copied to the request pool, so that it is durably allocated while the request exists.
This prevents futher mishaps. The server already has an equivalent function for its response object.
