When registering helpers via FFI for TCI, the inner loop that iterates
parameters of the helper reuses (and thus pollutes) the same variable
used by the outer loop that iterates all helpers, thus made some helpers
unregistered.
Fix this logic error by using a dedicated temporary variable for the
inner loop.

Commit 8801ccd050 introduced a compilation failure with clang
version 10.0.0-4ubuntu1:
../../net/vhost-vdpa.c:654:16: error: variable 'vdpa_device_fd' is
used uninitialized whenever 'if' condition is false
[-Werror,-Wsometimes-uninitialized]
} else if (opts->has_vhostfd) {

../../net/vhost-vdpa.c:629:23: note: initialize the variable
'vdpa_device_fd' to silence this warning
int vdpa_device_fd;
^
= 0
1 error generated.
It's a false positive -- the compiler doesn't manage to figure out
that the error checks further up mean that there's no code path where
vdpa_device_fd isn't initialized. Put another way, the problem is
that we check "if (opts->has_vhostfd)" when in fact that condition
must always be true. A cleverer static analyser would probably warn
that we were checking an always-true condition.
Fix the compilation failure by removing the unnecessary if().

Rather than registering the reset handler via a function which
appends the handler to a global list, prefer to implement it as

Back then, MIPSr6 was not supported (added in binutils commit
7361da2c952 during 2014 [2]).
Binutils codebase diverged so much over the last 18 years, it is
not possible to simply cherry-pick their changes, so fix it BEQZC /
BNEZC 21-bit signed branch displacement locally.

Since there's no support for exception handling in C, the try-catch
blocks have been deleted, and throw clauses are replaced. When a runtime
error happens, we're printing out the error message. Disassembling of
the current instruction interrupts. This behavior is achieved by adding
sigsetjmp() to discard further disassembling after the error message
prints and by adding the siglongjmp() function to imitate throwing an
error. The goal was to maintain the same output as it was.

This patch expands the Dis_info struct, which should hold the
necessary data for handling runtime errors. Fields fprintf_func and
stream are in charge of error printing. Field buf enables the use of
sigsetjmp() and siglongjmp() functions. Support for runtime error
handling will be added later.
We're filling Dis_info at the entrance of the nanoMIPS disassembler,
i.e. print_insn_nanomips. Next, we're adding that information as an
argument wherever we need to.

Disassemble function that calls the other variant of it is deleted.
Where it is called, now we're directly calling the other implementation.

g_autofree attribute is added for every dynamically allocated string to
prevent memory leaking.
The implementation of the several functions that work with dynamically
allocated strings is slightly changed so we can add those attributes.

CPR functions has been removed.
Before this patch, we'd been calling img_format twice, the first time
through the CPR function to get an appropriate string and the second
time to print that formatted string. There's no more need for that.
Therefore, calls to CPR are removed, and now we're directly printing
"CP" and integer value instead.
