The process-wide memory usage statistics of sqlite library is added to chrome://tracing. The memory usage of sqlite library is mainly through sqlite_malloc. The total usage of the process is recorded by sqlite3_memory_used() api. This CL also adds per-connection memory usage to tracing. Each connection uses memory for cache, schema and statement, and these usages are recorded. sqlit3_malloc uses malloc internally to allocate memory. So, thie memory is traced as sub-allocation from system_allocator(malloc). This CL lets us keep track of sqlite memory usage in chrome telemetry.
