95: Pass a0..a2 to main() r=almindor a=Disasm

This PR delivers arguments stored in a0..a2 to `main`.

Fixes https://github.com/rust-embedded/riscv-rt/issues/92



Tested with:
* build the `empty` example for `riscv64imac-unknown-none-elf` with a memory file which puts everything to `0x80000000`
* run `qemu-system-riscv64 -nographic -machine virt -bios target/riscv64imac-unknown-none-elf/release/examples/empty -s -S`
* connect to qemu with gdb (`target remote :1234`)
* set breakpoint to main (`b main`)
* resume execution (`continue`)
* inspect registers (`info registers`)
```
a0             0x0	0
a1             0x87000000	2264924160
a2             0x1028	4136
```
* check header (`x/xw 0x87000000`)
```
0x87000000:	0xedfe0dd0

93: Rerun the build script if the bin/{}.a archive has changed r=Disasm a=SimonSapin

This PR also includes some drive-by cleanup commits, but the last one is what’s significant. This bit me when trying to make changes to `asm.S` and rebuilding with `./assemble.sh`.

(By the way, I get ``Assembler messages: Fatal error: invalid -march= option: `rv32i'`` when running that script on Arch Linux despite installing a GNU toolchain for RISC-V. Instead I’m now using an Ubuntu 20.04 container to run it, since that’s what CI does for `./check-blobs.sh`.)

91: Don't use a random hash ident, instead use the crate prefixed symbol r=almindor a=MabezDev

This is what cortex-m land is doing. This was initially discovered to be an issue when implementing unwinding in riscv probe-rs, the dwarf info shows the hashed symbol name which is a bit weird, this makes it more clear what the symbol actually is.

81: Trap handler override improvments r=almindor a=MabezDev

* Add ability to override trap handling mechanism
  * Previously, `_start_trap` was marked as weak, which when compiled
    into a static archive, that information is ignored.
  * Now by default we `PROVIDE` the default trap handler, if another one
    has not been specified from another crate.
* Mark the fields of `Vector` public, for use outside of `riscv-rt`

79: update to riscv 0.7 r=almindor a=smsxgli

hi everyone, I am a new guy with both github, rust and riscv, and this is my first PR, so if I miss something or do something wrong, please let me know (and forgive my poor english, since I am not a native speaker).
crate `riscv` v0.7 solved link error about [`different hardware float abi`](https://github.com/rust-embedded/riscv/issues/85

), but riscv-rt still depend on `riscv` v0.6.
