be9d4f04 Fix multiline wallet cli output with readline (Jethro Grassie)
readline_buffer: fix start/stop threads being starved by process
process could run for quite some time re-acquiring the process
lock, leaving start/stop starving. Yielding after unlock in
process is much better but doesn't seem to be enough to reliably
yield, so we sleep for a millisecond, which should be transparent
for user input anyway.

monero-wallet-cli commands which have multine output sometimes causes
issues with the readline support. This patch fixes show_transfers,
payments and incoming_transfers.
Existing tests: block, transaction, signature, cold outputs,
cold transaction.
Data for these is in tests/data/fuzz.
A convenience shell script is in contrib/fuzz_testing/fuzz.sh, eg:
contrib/fuzz_testing/fuzz.sh signature
The fuzzer will run indefinitely, ^C to stop.
Fuzzing is currently supported for GCC only. I can't get CLANG
to build Monero here as it dies on some system headers, so if
someone wants to make it work on both, that'd be great.
In particular, the __AFL_LOOP construct should be made to work
so that a given run can fuzz multiple inputs, as the C++ load
time is substantial.

It'd eat up a core constantly, due to spending its time jumping
back and forth between userland and kernel. We now wait for up
to a millisecond in kernel, which will be transparent to the user
and drop to idle most of the time.
This PR adds readline support to the daemon and monero-wallet-cli. Only
GNU readline is supported (e.g. not libedit) and there are cmake checks
to ensure this.
There is a cmake variable, Readline_ROOT_DIR that can specify a
directory to find readline, otherwise some default paths are searched.
There is also a cmake option, USE_READLINE, that defaults to ON. If set
to ON, if readline is not found, the build continues but without
readline support.
One negative side effect of using readline is that the color prompt in
the wallet-cli now has no color and just uses terminal default. I know
how to fix this but it's quite a big change so will tackle another time.
A timedsync is issued every minute on a connection, but the input
tineout is 2 minutes. This means a new sync request could be issued
while a slow sync request was already in progress. The additional
request will further clog the network on a slow connection, and
cause a premature timeout.
All code which was using ip and port now uses a new IPv4 object,
subclass of a new network_address class. This will allow easy
addition of I2P addresses later (and also IPv6, etc).
Both old style and new style peer lists are now sent in the P2P
protocol, which is inefficient but allows peers using both
codebases to talk to each other. This will be removed in the
future. No other subclasses than IPv4 exist yet.
- Performance improvements
- Added `span` for zero-copy pointer+length arguments
- Added `std::ostream` overload for direct writing to output buffers
- Removal of unused `string_tools::buff_to_hex`
Because some people just won't even try to read what is written
and freak out because the word FATAL is in here, despite the
context making it clear it's not an error.
