On a QSFPTEK QT-SFP+-T (RTL8261C) 10GBase-T module, the diag type field (92) comes back as 0x00, but there's actually some statistics available like temperature. Other metrics may be hard-coded values. Add a basic struct that allows matching on vendor and/or model, using a bitfield to allow multiple quirks for a given SFP module. Only SFP_QUIRK_DDM is implemented. For modules matching SFP_QUIRK_DDM, attempt an I2C read of the MSB of module voltage during probe if DDM is "unsupported" - if it's not 0xff, override the reported options so we can pull the diagnostic data. To allow simpler comparisons, convert the ASCII fields (vendor, model, serial) from space-padded to standard NULL-terminated strings. strcmp() is moved from httpd.c to rtlplayground.c alongside other string functions and shared between them. The __reentrant keyword is used for the new functions to avoid using up additional OSEG space. This allocates the variables on the stack, which is OK for this particular code path. The JSON assembly in send_status() is slightly modified to treat the sfp_module_* data as standard NULL-terminated strings, and a repeated subtraction was moved into a uint8_t to declutter the code.
