Bump smallvec from 0.6.7 to 0.6.14 in /proxy

[dependabot]

Bumps smallvec from 0.6.7 to 0.6.14.

Release notes

Sourced from smallvec's releases.

v0.6.14

• Fix a possible buffer overflow in insert_many (#252, #254).

v0.6.13

• Use the maybe-unit crate in place of soon-to-be-deprecated std::mem::uninitialized (#180). When built with Rust 1.36 or later, this fixes a source of undefined behavior. It also fixes deprecation warnings in Rust 1.39 and later, and test failures when run in MIRI. In Rust 1.35 and earlier it provides some safety improvements but does not completely eliminate undefined behavior. (However, we are not aware of any cases where the undefined behavior causes bugs in practice in those toolchains.)

v0.6.12

• Move code using default fn into its own module (#161).

v0.6.11

• The unstable alloc feature is no longer needed. This crate can now build with the std feature disabled on stable Rust 1.36 or later (#159).

v0.6.10

• Fix a bug in extend with certain iterators (#150).
• Fix soundness bugs in the grow method (#151, #152).
• Fix typo in docs (#144).

v0.6.9

• Remove dependency on unreachable crate (#140)

v0.6.8

• Don't leak memory if an iterator panics during extend (#137)
• Update the unstable union feature for better forward compatibility (#135)
