Java GC evicts all SoftReferences when the used heap size comes close to
the maximum heap size. This means peaks in heap memory consumption can
flush the complete WindowCache which was observed to have negative
impact on performance of upload-pack in Gerrit.
Hence add a boolean option core.packedGitUseStrongRefs to allow using
strong references to reference packfile pages cached in the WindowCache.
If this option is set to true Java gc can no longer flush the
WindowCache to free memory if the used heap comes close to the maximum
heap size. On the other hand this provides more predictable performance.

Using exceptions during normal operations - for example with the
desire of expanding an array in the failure case - can have a
severe performance impact. When exceptions are instantiated,
a stack trace is collected. Generating stack trace can be expensive.
Compared to that, checking an array for length - even if done many
times - is cheap since this is a check that can run in just a
handful of CPU cycles.

Protected field ReceivePack.connectivityChecker is of type
ConnectivityChecker which was located in internal package
org.eclipse.jgit.transport and was thus leaking an internal type.
In order to fix this move ConnectivityChecker to package
org.eclipse.jgit.transport.

SSLContext.getInstance("TLS") by default behaves differently on IBM
JDK than on Oracle or OpenJDK.[1] On IBM JDK one gets sockets that
have only TLSv1 enabled, which makes HTTPS connections fail since most
servers refuse this old protocol version. On Oracle JDK/OpenJDK, one
gets sockets with all available protocol versions enabled.
Explicitly enable all available TLS protocol versions to make
HTTPS connections work also on IBM JDK.

Calling sh -c with a script path containing backslashes may fail since
the shell may try to process them as escape characters.
Instead of calling
sh.exe -c 'C:\path\script "$@"' 'C:\path\script' other args
call
sh.exe -c '$0 "$@"' 'C:\path\script' other args
which avoids this escape processing.
Note that this is not specific to Windows. If the path or the script
name contain backslashes, this also occurs on Unix.
