I was bumping against some blocksync performance issues with 12k+ keys, 24k+
scriptpubkeys being checked against, and migrating that list to a hashset is
an easy fix to shave off 99% of the time to process a block.

Pubkeys are not not actually DER encoding, but Pieter Wuille corrected
me: it's SEC 1 documented encoding.

Christian and I both unwittingly used it in form:
*tal_arr_expand(&x) = tal(x, ...)
Since '=' isn't a sequence point, the compiler can (and does!) cache
the value of x, handing it to tal *after* tal_arr_expand() moves it
due to tal_resize().
The new version is somewhat less convenient to use, but doesn't have
this problem, since the assignment is always evaluated after the
resize.

We do this a lot, and had boutique helpers in various places. So add
a more generic one; for convenience it returns a pointer to the new
end element.
I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.

tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

structeq() is too dangerous: if a structure has padding, it can fail
silently.
The new ccan/structeq instead provides a macro to define foo_eq(),
which does the right thing in case of padding (which none of our
structures currently have anyway).
Upgrade ccan, and use it everywhere. Except run-peer-wire.c, which
is only testing code and can use raw memcmp(): valgrind will tell us
if padding exists.
Interestingly, we still declared short_channel_id_eq, even though
we didn't define it any more!

Transaction filters are strongly related to the wallet, this move just
makes it a bit more explicit.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
This is mainly used to filter for transactions that may be of interest
to us, i.e., whether one of our keys is the recipient. It currently
does onyl simple scriptpubkey checks, but will eventually be extended
to use bloomfilters and add more sophisticated checks.
For now the goal is to speed up the processing of blocks during startup.
