Update IPsec.h file to follow approved ECR which will be collected into future UEFI 2.3 Specification after 2.3 errata B and future UEFI Specifications after 2.3. The changes mainly include:

Browse Source 
1. Add EFI_IPSEC2_PROTOCOL
  2. Remove IPsec Authentication Algorithm Definition and IPsec Encryption Algorithm    
     Definition.
  3. Add EFI_IPSEC_SA_DATA2 data structure.
And also update IPv4 driver to call EFI_IPSEC2_PROTOCOL.

/**
The function frees the net buffer which allocated by the IP protocol. It releases
only the net buffer and doesn't call the external free function.
This function should be called after finishing the process of mIpSec->ProcessExt()
for outbound traffic. The (EFI_IPSEC2_PROTOCOL)->ProcessExt() allocates a new
buffer for the ESP, so there needs a function to free the old net buffer.
@param[in] Nbuf The network buffer to be freed.
