remove cargo-snapshot* unpacker, it was needed
for separate dev-util/cargo we used to have.

# @ECLASS-VARIABLE: CARGO_OPTIONAL
# @DEFAULT_UNSET
# @PRE_INHERIT
# @DESCRIPTION:
# If set to a non-null value, before inherit cargo part of the ebuild will
# be considered optional. No dependencies will be added and no phase
# functions will be exported.
#
# If you enable CARGO_OPTIONAL, you have to set BDEPEND on virtual/rust
# for your package and call at least cargo_gen_config manually before using
# other src_ functions of this eclass.
# note that cargo_gen_config is automatically called by cargo_src_unpack.
# @ECLASS_VARIABLE: myfeatures
# @DEFAULT_UNSET
# @DESCRIPTION:
# Optional cargo features defined as bash array.
# Should be defined before calling cargo_src_configure().
#
# Example package that has x11 and wayland as features, and disables default.
# @CODE
# src_configure() {
# local myfeatures=(
# $(usex X x11 '')
# $(usev wayland)
# )

# @ECLASS-VARIABLE: ECARGO_REGISTRY_DIR
# @USER_VARIABLE
# @DEFAULT_UNSET
# @DESCRIPTION:
# Storage directory for cargo registry.
# Used by cargo_live_src_unpack to cache downloads.
# This is intended to be set by users.
# Ebuilds must not set it.
#
# Defaults to "${DISTDIR}/cargo-registry" it not set.
# @ECLASS-VARIABLE: ECARGO_OFFLINE
# @USER_VARIABLE
# @DEFAULT_UNSET
# @DESCRIPTION:
# If non-empty, this variable prevents online operations in
# cargo_live_src_unpack.
# Inherits value of EVCS_OFFLINE if not set explicitly.
# @ECLASS-VARIABLE: EVCS_UMASK
# @USER_VARIABLE
# @DEFAULT_UNSET
# @DESCRIPTION:
# Set this variable to a custom umask. This is intended to be set by
# users. By setting this to something like 002, it can make life easier
# for people who use cargo in a home directory, but are in the portage
# group, and then switch over to building with FEATURES=userpriv.
