Log:
Change serialization of doubles in the dbi backend to use 
g_ascii_dtostr() instead of sprintf. 

The problem is that sprintf is subject to localization and will output 
e.g. 1,25 for one-and-a-quarter in European locales. SQL doesn't support 
localization, so will interpret 1,25 as two fields, 1 and 25.

Note also that GUID_ENCODING_LENGTH isn't big enough for a double, so 
that's changed to G_ASCII_DTOSTR_BUF_SIZE.
