Instructions for Solaris

Use tests/all script to run all tests

Correct spelling of Erik's last name
Improve test framework: Solaris bug

The 'includeTests' function failed if /bin/bash was not available or not
the same as the Bash used to run the top test script.  This failed on
Solaris, where /usr/bin/bash is too old, and a privately-built Bash must
be used to run the test scripts.

Fix SEGV bug in keyring_enter_pin()

The public and private key length fields were stored as 'int' not

Fix keyring SEGV bug

Sometimes, when adding a PIN to a keyring (eg, when opening a keyring
file), a SEGV would be caused while trying to validate the MAC for an
entry which apparently had zero keypair entries.

Changed some keyring struct 'int' fields to 'unsigned int', to ensure
that comparison logic behaves as expected.

Refactored some keyring code for more clarity and code maintenance
safety.

Added TODO comment about keyring file format non-back-compatibility.
