Check for unreasonable alloc size in LockedPool rather than lancing through new
Arenas until we improbably find one worthy of the quixotic request or the system
can support no more Arenas.

Fixes newly initialized bloom filters being
constructed with isEmpty(false), which still
works but loses the possible speedup when
checking for key membership in an empty filter.
This splits the output comparison for `bitcoin-tx` into two steps:
- First, check for data mismatch, parsing the data as json or hex
depending on the extension of the output file
- Then, check if the literal string matches
For either of these cases give a different error.
This prevents wild goose chases when e.g. a trailing space doesn't match
exactly, and makes sure that both test output and examples are valid
data of the purported format.

getmemoryinfo
Returns an object containing information about memory usage.
Result:
{
"locked": { (json object) Information about locked memory manager
"used": xxxxx, (numeric) Number of bytes used
"free": xxxxx, (numeric) Number of bytes available in current arenas
"total": xxxxxxx, (numeric) Total number of bytes managed
"locked": xxxxxx, (numeric) Amount of bytes that succeeded locking. If this number is smaller than total, locking pages failed at some point and key data could be swapped to disk.
}
}
Examples:
> bitcoin-cli getmemoryinfo
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getmemoryinfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
```
Add a pool for locked memory chunks, replacing LockedPageManager.
This is something I've been wanting to do for a long time. The current
approach of locking objects where they happen to be on the stack or heap
in-place causes a lot of mlock/munlock system call overhead, slowing
down any handling of keys.
Also locked memory is a limited resource on many operating systems (and
using a lot of it bogs down the system), so the previous approach of
locking every page that may contain any key information (but also other
information) is wasteful.

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.
> This new feature is enabled by default if Bitcoin Core is listening, and a connection to Tor can be made. It can be configured with the -listenonion, -torcontrol and -torpassword settings. To show verbose debugging information, pass -debug=tor.
But it is correct to say that the feature is enabled *regardless* of whether a connection to Tor can be made.
I propose to clarify that so that users can eliminate these in their logs (when `listen=1` and no Tor).
And I think it's okay to clarify about the `listen` option, because on several occasions when I read this before I always assumed `listening` meant `server=1` which cost me a lot of time in troubleshooting.
