[PATCH 0/2] compile ipsec on Windows

[PATCH 0/2] compile ipsec on Windows

[Andre Muezerie]

Removed VLA for compatibility with MSVC (which does not support VLAs).
Used alloca when a constant fixed length that can be used instead is
not known.

Implementation for rte_ipsec_pkt_crypto_group and
rte_ipsec_ses_from_crypto was moved to new file
lib\ipsec\ipsec_group.c because these functions get exported in a
shared library (lib\ipsec\version.map).

Implementation for rte_ipsec_pkt_crypto_prepare and
rte_ipsec_pkt_process was moved to new file lib\ipsec\ipsec.c because
these functions get exported in a shared library
(lib\ipsec\version.map).

Removed logic which was skipping ipsec on Windows.

[PATCH 2/2] app/test: enable ipsec-related tests

[Andre Muezerie]

Removed ifdefs which were bypassing the ipsec tests on Windows.

Removed "return" from void function to avoid warning on MSVC.
