Upgrade to v0.45

Change to use Cmake to build the C binding.

Upgrade to v0.42

The naming convention for C binding has been altered.

Struct Naming

Renaming certain struct names for consistency.

• opendal_operator_ptr => opendal_operator
• opendal_blocking_lister => opendal_lister
• opendal_list_entry => opendal_entry

API Naming

We‘ve eliminated the blocking_ prefix from our API because C binding doesn’t currently support async. In the future, we plan to introduce APIs such as opendal_operator_async_write.

• opendal_operator_blocking_write => opendal_operator_write
• opendal_operator_blocking_read => opendal_operator_read
