switch to libhermit 0.4.2 to remove some issues with the RTL8139 driver

revise network configuration by DHCP

Add block_current_task_with_timeout syscall

switch to libhermit v0.4.1

revise network interface

revise mutex interface

add user-level mutex

- this mutex is used by libstd
- support of priority inheritance to avoid priority inversion

Upgrade to Rust 2021

- increase major number of hermit-abi because this release requires
  2021 edition of Rust
- yank previous version => all previous versions are able to use
  older 2018 edition

Upgrade to Rust 2021

- Replace llvm-tools with cargo-binutils
- Replace deprecated target_build_utils
- Rename duplicate aarch64 symbols

Upgrade to Rust 2021

Migrate to CARGO_ENCODED_RUSTFLAGS

Cargo introduced CARGO_ENCODED_RUSTFLAGS in rust-lang/cargo#9601 to make setting flags less error prone – it encodes arguments separated by 0x1f (ASCII Unit Separator), instead of white spaces (old RUSTFLAGS).

CARGO_ENCODED_RUSTFLAGS are preferred over the old RUSTFLAGS in cargo. For build scripts, cargo converts its RUSTFLAGS to CARGO_ENCODED_RUSTFLAGS. For unset RUSTFLAGS it is set to an empty string. Thus our build script would call cargo for building libhermit-rs with a set – but empty – CARGO_ENCODED_RUSTFLAGS, which takes precedence over our prepared RUSTFLAGS. Specifically this caused our -Zmutable-noalias=no flag to be ignored, causing the same network issue as #128 again.

This PR adjusts our build script to make direct use of CARGO_ENCODED_RUSTFLAGS, the new and preferred way of handling flags in build scripts. This causes our flags to be correctly handled again.

redesign of the network interface

- using async tasks to check the network device

resolve clippy lints

rename panic function to avoid conflicts with libstd

introducing the new target of kernel interface

add basic DHCP support

- add basic DHCP support #102
- add option to enable VGA support #101
- add feature flag to enable/disable smp support #93

Allow hermit-abi to build without std

This makes crates depending on hermit-abi able to check their build by
just using `-Zbuild-std=core` instead of needing all of `-Zbuild-std`.

Also, remove an unnecessary feature that isn't used anywhere.

add option to disable/enable the PCI/ACPI support

add missing cmath symbols
