Now:
1) If mmu is disabled, virt2phys succeeded and returns physical address
2) If mmu is enbaled, but translation fails, read/write_memory fails

`riscv_debug_reg_to_s()` can be used to decode register value. If the
pointer to buffer is `NULL` it does not print anything, just returns the
length of the string.
The format is:
`<register_value> { <field_name>=<field_value_name or field_value>, ..., }`
e.g:
`0x400382 { version=2, ... ndmresetpending=false, }`
`0x321009 { regno=0x1009, ... cmdtype=0, }`

When the target isn't halted, simply return an error. This used to be
purely internal code so an assert was appropriate. Now after some
refactoring and with unavailable harts you could get here when the hart
is unavailable. In that case the right thing is simply to return an
error message.

Previously, an unknown semihosting operation number
was logged as debug. This patch changes it and few
other places to be logged as error instead.

During a previous patch, the ignoring of writes to register zero
was deleted. This patch restores it to the original.

This also fixes a bug when, after `examine` completion, the target still
has `unknown` status. To reproduce this one spike, it is enough to do
the following:
---
// make sure spike harts are halted
openocd ... -c init -c 'echo "[targets]"'
---
this behavior is quite dangerous and leads to segfaults in some cases
