LibGit2Sharp v0.22.1

This is a security release fixing two issues. The first one performs extra sanitization for some edge cases in the Git Smart Protocol which can lead to attempting to parse outside of the buffer.

The second fix affects the certificate check callback. It provides a valid parameter to indicate whether the native cryptographic library considered the certificate to be correct. This parameter is always 1/true before this fix leading to a possible MITM.

This does not affect you if you do not use the custom certificate callback or if you do not take this value into account.
