Marcin Spiewak ceb3747451 configure: added --max-lcores option to ./configure 
This patch adds support for --max-lcores configuration
option to ./configure script. This option can be
used to change value of DPDK's RTE_MAX_LCORE
(which is by default set to 128 for x86 architecture).
If specified, DPDK will be configured to use
the value provided by the user instead of
the default one. The option can be useful
in systems where number of physical CPUs is
larger than 128.
When RTE_MAX_LCORE is increased, it is possible
to specify cores with identifiers larger than
128 in the SPDK's CPU mask.
If the option is not specifed, DPDK will use
default value of RTE_MAX_LCORE.
--max-lcores range is [1..1024]
Example usage:
./configure --max-lcores=256
./configure --max-lcores=16
