Revert r347402. After r347429 symlink is no longer needed.
Add if_ipsec.ko symlink to ipsec.ko kernel module.This add ability to automatically load ipsec kernel module, whenif_ipsec(4) virtual interface is created using ifconfig(8).Reviewed by: gallatin

Merge projects/ipsec into head/. Small summary -------------o Almost all IPsec releated code was moved into sys/netipsec.o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel option IPSEC_SUPPORT added. It enables support for loading and unloading of ipsec.ko and tcpmd5.ko kernel modules.o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type support was removed. Added TCP/UDP checksum handling for inbound packets that were decapsulated by transport mode SAs. setkey(8) modified to show run-time NAT-T configuration of SA.o New network pseudo interface if_ipsec(4) added. For now it is build as part of ipsec.ko module (or with IPSEC kernel). It implements IPsec virtual tunnels to create route-based VPNs.o The network stack now invokes IPsec functions using special methods. The only one header file <netipsec/ipsec_support.h> should be included to declare all the needed things to work with IPsec.o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed. Now these protocols are handled directly via IPsec methods.o TCP_SIGNATURE support was reworked to be more close to RFC.o PF_KEY SADB was reworked: - now all security associations stored in the single SPI namespace, and all SAs MUST have unique SPI. - several hash tables added to speed up lookups in SADB. - SADB now uses rmlock to protect access, and concurrent threads can do SA lookups in the same time. - many PF_KEY message handlers were reworked to reflect changes in SADB. - SADB_UPDATE message was extended to support new PF_KEY headers: SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They can be used by IKE daemon to change SA addresses.o ipsecrequest and secpolicy structures were cardinally changed to avoid locking protection for ipsecrequest. Now we support only limited number (4) of bundled SAs, but they are supported for both INET and INET6.o INPCB security policy cache was introduced. Each PCB now caches used security policies to avoid SP lookup for each packet.o For inbound security policies added the mode, when the kernel does check for full history of applied IPsec transforms.o References counting rules for security policies and security associations were changed. The proper SA locking added into xform code.o xform code was also changed. Now it is possible to unregister xforms. tdb_xxx structures were changed and renamed to reflect changes in SADB/SPDB, and changed rules for locking and refcounting.Reviewed by: gnn, wblockObtained from: Yandex LLCRelnotes: yesSponsored by: Yandex LLCDifferential Revision: https://reviews.freebsd.org/D9352
