Delete the old branch and pull a new one, because of a wrong force push. Git is not as easy as I think.

This replaces multiple uses of `std::vector::operator[]` where the
parameter is a constant `0` with the use of C++11's `std::vector::data`
method. This fixes the root cause of invalid memory accesses.
`std::vector::operator[]` is an unchecked memory access, and when the
buffers are zero-sized (that is the buffer container is empty) either
due to a 0 padding in the case of elfloader or NULL parameters to
syscalls where permitted, the unchecked access may cause an invalid
memory access. The use of `std::vector::data` is permitted even in such
a case, though the returned memory may not be dereferenced. The general
usage of the returned pointer is to pass to `memif_t`, which is careful
about 0-sized buffer accesses, and so passing the result of
`std::vector::data` is safe. This is theoretically a better access
pattern as it also avoids having the compiler to re-materialize the
pointer from the de-referenced location.
* reduce sig_len constraint to 4 bytes
Spike currently asserts that the signature length should always be a multiple of 16-bytes. However, the compliance suite has agreed to upon the signature being a multiple ot 4-bytes. This prevents some of the tests to run on spike since it fails the assertion.
The proposed change fixes this issue and reduces the assertion to 4 bytes.
* Added size argument to htif arguments and zero padding for signature output. Defaultline size-16.
* Modified type of line_size to unsigned.
* Renamed size to granularity.
* Rename granularity to signature-granularity.

* Adding symbol lookup when --enable-commitlog is enabled
* Removed the #ifdef RISCV_ENABLE_COMMITLOG for all get_symbol related function
Only retained the in processor.cc where it is called.

Firmware implementations, such as OpenSBI's fw_jump, make use of this
feature on other targets to avoid having to be rebuilt every time the
payload is updated.
