ISSUE:       8066
TITLE:       Make protocol schemes case-insensitive
DESCRIPTION:
    Test iterates over all possible protocols (depending on OS and engine major version): INET(4|6), WNET, XNET.
    Then connection string is made using three cases of protocol string: lower, UPPER and Capitalized.
    For each kind of DSN we request mon$attachment.mon$remote_protocol value - it must correspond to DSN but 
    always must be in upper case.
    Expected output must not contain any error and must contain appropriate values for every checked protocol
    (see 'mon_remote_value')
    We have to construct this string 'on the fly' because avaliable protocols depend on OS and major version
    (see 'expected_out_lines')
NOTES:
    [06.05.2024] pzotov
    Checked on 6.0.0.344, 5.0.1.1394, 4.0.5.3091.

    [08.05.2024] pzotov
    Removed check of 'inet' (w/o digital suffix): value in mon$remote_process can be either 'TCPv4' or 'TCPv6'
    depending on Control Panel/Network and Internet/Network Connections settings.
    Connection to localhost *can* be established using IPv6 even if appropriate item has been disabled in
    network interface settings. 
    In this case 'connect inet://<alias>' causes mon$remote_address = 'TCPv4' - in contrary to 'TCPv6'
    when IPv6 is enabled.
