p2p: fix frequent weak_ptr exception on connection
When a handshake fails, it can fail due to timeout or destroyed
connection, in which case the connection will be, or already is,
closed, and we don't want to do it twice.
Additionally, when closing a connection directly from the top
level code, ensure the connection is gone from the m_connects
list so it won't be used again.

AFAICT this is now clean in netstat, /proc/PID/fd and print_cn.

This fixes a noisy (but harmless) exception.

levin: armour against some "should not happen" case
If adding a response handler after the protocol is released,
they could never be cancelled again, and would end up keeping

levin_protocol_handler_async: tune down preallocation a fair bit
It can allocate a lot when getting a lot of connections
(in particular, the stress test on windows apparently pushes
that memory to actual use, rather than just allocated)

Fix an object lifetime bug in net load tests
The commands handler must not be destroyed before the config
object, or we'll be accessing freed memory.

An earlier attempt at using boost::shared_ptr to control object
lifetime turned out to be very invasive, though would be a
better solution in theory.

epee: keep a ref to a connection we're deleting
close might end up dropping a ref, ending up removing the
connection from m_connects, as the lock is recursive. This'd
cause an out of bounds exception and kill the idle connection

Change logging to easylogging++
This replaces the epee and data_loggers logging systems with
a single one, and also adds filename:line and explicit severity
levels. Categories may be defined, and logging severity set
by category (or set of categories). epee style 0-4 log level
maps to a sensible severity configuration. Log files now also
rotate when reaching 100 MB.

To select which logs to output, use the MONERO_LOGS environment
variable, with a comma separated list of categories (globs are
supported), with their requested severity level after a colon.
If a log matches more than one such setting, the last one in
the configuration string applies. A few examples:

This one is (mostly) silent, only outputting fatal errors:

MONERO_LOGS=*:FATAL

This one is very verbose:

MONERO_LOGS=*:TRACE

This one is totally silent (logwise):

MONERO_LOGS=""

This one outputs all errors and warnings, except for the
"verify" category, which prints just fatal errors (the verify
category is used for logs about incoming transactions and
blocks, and it is expected that some/many will fail to verify,
hence we don't want the spam):

MONERO_LOGS=*:WARNING,verify:FATAL

Log levels are, in decreasing order of priority:
FATAL, ERROR, WARNING, INFO, DEBUG, TRACE

Subcategories may be added using prefixes and globs. This
example will output net.p2p logs at the TRACE level, but all
other net* logs only at INFO:

MONERO_LOGS=*:ERROR,net*:INFO,net.p2p:TRACE

Logs which are intended for the user (which Monero was using
a lot through epee, but really isn't a nice way to go things)
should use the "global" category. There are a few helper macros
for using this category, eg: MGINFO("this shows up by default")
or MGINFO_RED("this is red"), to try to keep a similar look
and feel for now.

Existing epee log macros still exist, and map to the new log
levels, but since they're used as a "user facing" UI element
as much as a logging system, they often don't map well to log
severities (ie, a log level 0 log may be an error, or may be
something we want the user to see, such as an important info).
In those cases, I tried to use the new macros. In other cases,
I left the existing macros in. When modifying logs, it is
probably best to switch to the new macros with explicit levels.

The --log-level options and set_log commands now also accept
category settings, in addition to the epee style log levels.

levin: fix wrong value passed as return code to remote call
When receiving an answer packet, the command code was passed
to the callback instead of the error code. This was hiding
the "command not found" failure from the peer, and in turn
causing the code to attempt to deserialize a non existent
reply string.
