log: colorize log output

Like dmesg, colorize the log output (unless redirected to file).
Timestamp is green, the subsystem is in yellow and the message is red
if urgent, boldface if an error, and normal for info and debug messages.

The default is to not use color since it may disturb automatic tests
and other embedded usage.

Note: add fileno() and isatty() to the Windows wrapper.

log: add timestamp option

When debugging driver or startup issues, it is useful to have a timestamp
on each message printed.
The messages in syslog already have a timestamp, but often syslog is not
available during testing.

There are multiple timestamp formats similar to Linux dmesg.
The default is time relative since startup (when first step of logging
initialization is done by constructor).
Other alternative formats are delta, ctime, reltime and iso formats.

Example:
$ dpdk-testpmd --log-timestamp -- -i
[ 0.008610] EAL: Detected CPU lcores: 8
[ 0.008634] EAL: Detected NUMA nodes: 1
[ 0.008792] EAL: Detected static linkage of DPDK
[ 0.010620] EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
[ 0.012618] EAL: Selected IOVA mode 'VA'
[ 0.016675] testpmd: No probed ethernet devices
Interactive-mode selected

Note: Windows does not have localtime_r but it does have a similar
function that can be used instead. Add it to rte_os_shim.h.

eal/linux: allocate worker lcore stacks in hugepages

Add support for using hugepages for worker lcore stack memory. The
intent is to improve performance by reducing stack memory related TLB
misses and also by using memory local to the NUMA node of each lcore.

EAL option '--huge-worker-stack[=stack-size-in-kbytes]' is added to allow
the feature to be enabled at runtime. If the size is not specified,
the system pthread stack size will be used.

lib: remove librte_ prefix from directory names

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
