It is easier to find all constructor functions when they use
the same macros RTE_INIT or RTE_INIT_PRIO.
The macro definitions are moved from rte_eal.h to rte_common.h.

When calibrating the TSC frequency, first, probe the architecture specific
function. If not available, use the existing calibrate scheme.

When running single-core, some drivers tend to call rte_delay_us for a
long time, and that is causing packet drops.
To avoid this, rte_delay_us can be replaced with user-defined delay
function with:
void rte_delay_us_callback_register(void(*userfunc)(unsigned));
When userfunc==rte_delay_us_block build-in blocking delay function is
restored.

Compiling for dpdk x86_x32 gives the following error:
In file included from /usr/include/sys/sysctl.h:63:0,
from lib/librte_eal/common/eal_common_timer.c:39:
/usr/include/bits/sysctl.h:19:3: error: #error "sysctl system call is unsupported in x32 kernel"
# error "sysctl system call is unsupported in x32 kernel"
^
Including sysctl.h was added by mistake when merging bsd and linux EAL
timer code. It can be safely removed in this file, fixing the
compilation.

Fix error where TSC freq is 0.
The logical OR operator evaluates to 1 if any of its operands is
different than 0.
Error showed later while initializing PMD:
EAL: TSC frequency is ~0 KHz

PMD: eth_ixgbe_dev_init(): Hardware Initialization Failure: -30

Move common functions from BSD/Linux to eal_common_timer.c.
BSD uses sysctl and Linux uses CLOCK_MONOTIC_RAW to calibrate TSC.
HPET is specific to Linux and not integrated in the common init.
