Use easylogging++'s stack trace facility where possible
This avoids using libunwind, which often causes trouble.

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.

core: move tx_extra parsing errors to log level 1
They're not fatal, though indicate something wrong

epee: flush output after a message
This is equivalent to line buffering, as C++ seems to lack
a setvbuf equivalent which alows line buffering.

epee: make log macros behave like statements
In particular, make this kind of thing do what one expects
it to do:

if (x) LOG_PRINT("True"); else LOG_PRINT("No");

epee: Don't set log file name when process path name isn't found
If process path name isn't found, then leave log file name blank.

This also applies if a process name is found, but it's blank after
removing a trailing dot extension.
