In verifyServerCertificate parse certificates using the global
certificate cache.
This should signficiantly reduce memory usage in TLS clients which make
concurrent connections which reuse certificates (anywhere in the chain)
since there will only ever be one copy of the certificate at once.

We use crypto/internal/edwards25519/field to implement X25519 directly,
so that golang.org/x/crypto/curve25519 can be dropped from the src
module dependencies, and eventually replaced with a crypto/ecdh wrapper,
removing the need to keep golang.org/x/crypto/curve25519/internal/field
in sync with crypto/internal/edwards25519/field.
In crypto/internal/nistec, we add BytesX to serialize only the x
coordinate, which we'll need for the horrible ECDSA x-coord-to-scalar
operation, too.
In crypto/tls, we replace the ECDHE implementation with crypto/ecdh,
dropping the X25519 special cases and related scaffolding.
Finally, FINALLY, we deprecate the ~white whale~ big.Int-based APIs of
the crypto/elliptic package. •_•) ( •_•)>⌐■-■ (⌐■_■)

As it can't appear in user package paths.
There is a hack for handling "go:buildid" and "type:*" on windows/386.
Previously, windows/386 requires underscore prefix on external symbols,
but that's only applied for SHOSTOBJ/SUNDEFEXT or cgo export symbols.
"go.buildid" is STEXT, "type.*" is STYPE, thus they are not prefixed
with underscore.
In external linking mode, the external linker can't resolve them as
external symbols. But we are lucky that they have "." in their name,
so the external linker see them as Forwarder RVA exports. See:
- https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#export-address-table
- https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/pe-dll.c;h=e7b82ba6ffadf74dc1b9ee71dc13d48336941e51;hb=HEAD#l972)
This CL changes "." to ":" in symbols name, so theses symbols can not be
found by external linker anymore. So a hacky way is adding the
underscore prefix for these 2 symbols. I don't have enough knowledge to
verify whether adding the underscore for all STEXT/STYPE symbols are
fine, even if it could be, that would be done in future CL.

This API was added only for BoringCrypto, never shipped in standard
Go. This API is also not compatible with the expected future evolution
of crypto/x509, as we move closer to host verifiers on macOS and Windows.
If we want to merge BoringCrypto into the main tree, it is best not to
have differing API. So instead of a hook set by crypto/tls, move the
actual check directly into crypto/x509, eliminating the need for
exposed API.
