Add error and range-checking parsers for unsigned 32 and 64 bit numbers.
The 32-bit variant is required for parsing sequence numbers from the
command line in `bitcoin-tx` (see #8164 for discussion). I've thrown in
the 64-bit variant as a bonus, as I'm sure it will be needed at some
point.
Also adds tests, and updates `developer-notes.md`.
This allows future software that would relay compact blocks before
full validation to announce only to peers that will not ban if the
block turns out to be invalid.
sync_with_ping() only guarantees that the node has processed messages
it's received from the peer, not that block announcements from the node have
made it back to the peer. Replace sync_with_ping() with an explicit check that
the node's tip has been announced.

Python lambda use was incorrect.
sendcmpct messages need to be synchronized with RPC calls to generate().
Headers need to be synced (eg with getheaders) for cmpctblock announcements
to start.
Last test omitted sending a sendcmpct message.

Add statement about MIT licensing to indirectmap.h. I forgot the license
preamble when I originally wrote the file.

This patch changes the implementation from one that stores 16 2-bit integers
in one uint32_t's, to one that stores the first bit of 64 2-bit integers in
one uint64_t and the second bit in another. This allows for 450x faster
refreshing and 2.2x faster average speed.
For each 'bit' in the filter we really maintain 2 bits, which store either:
0: not set
1-3: set in generation N
After (nElements / 2) insertions, we switch to a new generation, and wipe
entries which already had the new generation number, effectively switching
from the last 1.5 * nElements set to the last 1.0 * nElements set.
This is 25% more space efficient than the previous implementation, and can
(at peak) store 1.5 times the requested amount of history (though only
1.0 times the requested history is guaranteed).
The existing unit tests should be sufficient.
Use of node_network here is really meant to be a proxy of "likely to
send us blocks in the future". RelevantServices is the right criteria
now.

nMaxInbound might very well be 0 or -1, if the user prefers to keep
a small number of maxconnections.
Note: nMaxInbound of -1 means that the user set maxconnections
to 8 or less, but we still want to keep an additional slot for
the feeler connection.

We normally prefer to connect to peers offering the relevant services.
If we're not connected to enough peers with relevant services, we
probably don't know about them and could use dnsseed's help.

Only allow skipping relevant services until there are four outbound
connections up.
This avoids quickly filling up with peers lacking the relevant
services when addrman has few or none of them.

This makes sure that the event loop eventually terminates, even if an
event (like an open timeout, or a hanging connection) happens to be
holding it up.
along with mutex/condvar/bind/etc.
httpserver handles its own interruption, so there's no reason not to use std
threading.
While we're at it, may as well kill the BOOST_FOREACH's as well.
