net: TFTP: variables cleanup and addition
TFTP source and destination port variable names are 'tftpsrcp' and 'tftpdstp' in the code, but 'tftpsrcport' and 'tftpdstport' in the README file. Fix the README. Add environment variable 'tftptimeoutcountmax'. As per the comments about the global variable tftp_timeout_count_max, make sure tftptimeoutcountmax is nonnegative. Introduce configuration option CONFIG_NET_TFTP_VARS, which controls whether environment variables tftpblocksize, tftptimeout, and tftptimoueoutcountmax are read by the TFTP client code. CONFIG_NET_TFTP_VARS defaults to y but can be set to n by targets with to tight size contraints. Make bf527-ezkit set CONFIG_NET_TFTP_VARS to n to keep the target size below limit.
