Several files in the repository were tracked with execute permissions

GCC 7.2 is much stricter than previous GCC versions. The following changes
are needed:
* There is now a warning if there is an implicit fallthrough between two
case statments. C++17 adds the [[fallthrough]]; declaration. However,
to support non C++17 standards (i.e., C++11), we use M5_FALLTHROUGH.
M5_FALLTHROUGH checks for [[fallthrough]] compliant C++17 compiler and
if that doesn't exist, it defaults to nothing (no older compilers
generate warnings).
* The above resulted in a couple of bugs that were found. This is noted
in the review request on gerrit.
* throw() for dynamic exception specification is deprecated
* There were a couple of new uninitialized variable warnings
* Can no longer perform bitwise operations on a bool.
* Must now include <functional> for std::function
* Compiler bug for void* lambda. Changed to auto as work around. See
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82878

On exiting log types (panic and fatal), the message is set to an
ADD_FAILURE_AT macro, and the test is exited by throwing an otherwise
unexpected exception. On non-exiting log types, the message is sent to
the SUCCEEDED macro which currently doesn't output anything.

Removed the "verbose" switch which wasn't used.
Replaced the "get(LogLevel)" function with a get for each level. The
parameter was always constant, so we can just call the right function
at the right time.
Made the "exit" behavior of panic/fatal a part of the logging
implementation so that it can be overridden, and corrected a comment
which said that both fatal and panic called ::abort().
Got rid of the printEpilogue function by reworking the print() methods.
The subclasses of Logger can now override a "log" function which takes
a composed message, letting the Logger class centralize how the message
is put together and leaving the actual output mechanism to the
subclass.
Unfortunately there wasn't a way to tell gcc that the panic/fatal
macros wouldn't return, so there needed to be an exit_helper wrapper
function which calls the actual logger exit function. That can be
marked as noreturn, unlike the virtual exit function. If the exit
function does return, the wrapper will call ::abort(), placating gcc
and ensuring that even if exit isn't implemented properly, exit_helper
will still not return. That also provides a handy default
implementation.

Dumping the structure of the tries being constructed was useful for
debugging when the trie data structure was being developed, but the
output can't be automatically verified easily, and what's considered
correct depends on the specific implementation of the trie itself.
To make some of the earlier tests more meaningful, additional lookups
were added which verified that the correct values were returned when
the nodes of the trie were in particular arrangements.

Despite online documentation, the type used for sin_addr.s_addr is not
actually an unsigned long, it is an in_addr_t. When an unsigned long is a 64
bit value, the endian conversion moves the relevant bits of the 32 bit
in_addr_t to positions which are truncated away. This forces the value to 0
which means to bind to any interface, the opposite of the intended effect.

* Some templatized classes contain static variables. The

Currently, if the remote gdb stub fails to read a byte from an incoming
packet because the connection has been dropped, the read call will return
anyway and the calling code will have no way to know something bad
happened. It might reattempt the read over and over again waiting for some
particular byte, doomed to never make forward progress.
This change modifies the remote GDB code so that if a read or write call
fails, it will instead detach from the debugger and continue. Before this
change, When simulating a port scan, ie connecting to the debugger port
and then immediately dropping the connection using this command:
nc -v -n -z -w 1 127.0.0.1 7000
gem5 would enter the previously described death spiral. After it, gem5
detaches from the bad connection and resumes execution. Subsequently
attaching with gdb was successful.
This code is written in a C centric style, and would benefit from some
refactoring.

It's currently possible to change the log level in gem5 by tweaking a
set of global variables. These variables are currently exposed to
Python using SWIG. This mechanism is far from ideal for two reasons:
First, changing the log level requires that the Python world enables
or disables individual levels. Ideally, this should be a single call
where a log level is selected. Second, exporting global variables is
poorly supported by most Python frameworks. SWIG puts variables in
their own namespace and PyBind doesn't seem to support it at all.
This changeset refactors the logging code to create a more abstract
interface. Each log level is associated with an instance of a Logger
class. This class contains common functionality, an enable flag, and a
verbose flag.
Available LogLevels are described by the LogLevel class. Lower log
levels are used for more critical messages (PANIC being level 0) and
higher levels for less critical messages. The highest log level that
is printed is controlled by calling Logger:setLevel().

First of five patches adding RISC-V to GEM5. This patch introduces the
base 64-bit ISA (RV64I) in src/arch/riscv for use with syscall emulation.
The multiply, floating point, and atomic memory instructions will be added
in additional patches, as well as support for more detailed CPU models.
The loader is also modified to be able to parse RISC-V ELF files, and a
"Hello world\!" example for RISC-V is added to test-progs.
Patch 2 will implement the multiply extension, RV64M; patch 3 will implement
the floating point (single- and double-precision) extensions, RV64FD;
patch 4 will implement the atomic memory instructions, RV64A, and patch 5
will add support for timing, minor, and detailed CPU models that is missing
from the first four patches (such as handling locked memory).
[Removed several unused parameters and imports from RiscvInterrupts.py,
RiscvISA.py, and RiscvSystem.py.]
[Fixed copyright information in RISC-V files copied from elsewhere that had
ARM licenses attached.]
[Reorganized instruction definitions in decoder.isa so that they are sorted

[Fixed formatting of several files, removed some variables and
instructions that were missed when moving them to other patches, fixed
RISC-V Foundation copyright attribution, and fixed history of files
copied from other architectures using hg copy.]
[Fixed indentation of switch cases in isa.cc.]
[Reorganized syscall descriptions in linux/process.cc to remove large
number of repeated unimplemented system calls and added implmementations
to functions that have received them since it process.cc was first
created.]
[Fixed spacing for some copyright attributions.]

loaded .text secion is non-zero. This is useful in the general case as
an empty text section normally indicates that there is something
strange with the ELF file. However, asserting isn't very useful. This
changeset converts the assert into a warning that tells the user that
something strange is happening.

The SymbolTable class currently assumes that at most one symbol can
point to a given address. If multiple symbols point to the same
address, only the first one gets added to the internal symbol table
since there is already a match in the address table.
This changeset converts the address table from a map into a multimap
to be able to handle cases where an address maps to multiple
symbols. Additionally, the insert method is changed to not fail if
there is a match in the address table.
