Building on OS X: egg uses 1 deprecated function and 1 missing function

Description

Building the sqlite3 egg on OS X (10.11.6) produces a warning and an error -- see below for full trace.

Specifically:

'sqlite3_enable_shared_cache' has been explicitly marked deprecated here

The SQLite docs note https://www.sqlite.org/c3ref/enable_shared_cache.html that ‘This method is disabled on MacOS X 10.7 and iOS version 5.0 and will always return SQLITE_MISUSE’

Also, the function sqlite3_enable_load_extension appears not to be available on OS X. The SQLite docs https://www.sqlite.org/c3ref/enable_load_extension.html seem to recommend a different route to disabling this, on security grounds, but I confess I don't understand the implications of that. This function is still mentioned in the system sqlite3.h header, but it appears to be absent from (been deliberately removed from?) the system sqlite3 library.

There appear to be alternative documented routes to both of the intended functionalities, so I've tentatively marked this as 'easy' difficulty.

Building with:

chicken-install -n -D disable-shared-cache,disable-load-extension

appears to work OK, though I haven't tested fully.
