z b201154d17 csqlite: self-contained cgo SQLite bindings (fork of go-sqlite3)
Fork of github.com/mattn/go-sqlite3 v1.14.47, rebranded to package csqlite and
vendored in-tree (SQLite amalgamation sqlite3-binding.c/.h + cgo driver +
callback trampolines + optional-feature files) so the Hanzo stack depends on no
external go-sqlite3 module. Registers the "sqlite3" database/sql driver name
from this repo. SQLCipher at-rest encryption unchanged: link system libsqlcipher
via -tags libsqlite3.

Preserves upstream MIT license (LICENSE) with Hanzo-first NOTICE attribution.

Verified: CGO_ENABLED=1 build+test (amalgamation) green; -tags libsqlite3 +
libsqlcipher build+test green; CGO_ENABLED=0 build green; zero mattn in deps.

// usleep is a function available on *nix based systems.

// Windows has a sleep function but this works with seconds
// and not with microseconds as usleep.
//
// This code should improve performance on windows because
// without the presence of usleep SQLite waits 1 second.
