Ricardo Quesada e48043b095 elogtool: compile in 32-bit platforms
This CL fixes a compilation error that happens in 32-bit platforms.
This error happens because printf() was using %ld instead of %zu to
print size_t variables.

This CL fixes it.

Ricardo Quesada 683b294d3f elogtool: add "add" command
Adds "add" command to elogtool. This command allows adding elog events
manually. It supports event type and, optionally, event data.

If the free buffer space is < 1/4 of the total space, it shrinks the
buffer, making sure that ~1/4 of the free space is available.

TEST=./elogtool add 0x17 0101
     ./elogtool add 0x18
     Repeated the same tests on buffers that needed to be shrunk.

Ricardo Quesada a2bf94d4c1 elogtool: add next_available_event_offset function
This function is "extracted" from cmd_clear().
This new function will be called from cmd_add(), and new command that
will be added in a future CL (see CL chain).

Additional minor fixes:
 - calls usage() if no valid commands are passed.
 - Slightly improves usage() output. Needed for cmd_clear()

Ricardo Quesada 49a96a9463 elogtool: add "clear" command
Adds "clear" command to cbfsutil/elogtool tool.
"clear" clears the RW_ELOG region by using either:
 * flashrom if no file is provided
 * or using file write if an input file is provided.

The region is filled with ELOG_TYPE_EOL. And a
ELOG_TYPE_LOG_CLEAR event is inserted.

Additionally, it does a minor cleanup to command "list", like:
 * use buffer_end()
 * add "list" to the cmds struct
 * and make elog_read() very similar to elog_write()

Usage:
$ elogtool clear

BUG=b:172210863
TEST=elogtool clear && elogtool list
     elogtool clear -f invalid.raw
     elogtool clear -f valid.raw

Ricardo Quesada c2cf3946c9 util/elogtool: add tool to print elog events
Add a new tool that that prints elog events.
The tool, as input, accepts either a file with the RW_ELOG contents, or
if the file is not provided it reads the contents of RW_ELOG by calling
the "flashrom" tool.

The tool is based on "mosys eventlog list"[1]. For the moment it only
supports "list", but future commits will add additional functionality.

This commit also adds missing ELOG defines needed for the tool. These
defines are added with the rest of the ELOG defines, in
include/commonlib/bsd/elog.h

The tool is placed inside util/cbfstool. The rationale behind the
decision, is that this tool shares a lot in common with the other tools
located in cbfstool: vboot dependency, shared files like common.o and
valstr.o, and in spirit is similar to some of the tools located in
cbfstool/.

As an example, you call the tool like the following:

$ elogtool list -f rw_elog_dump.bin
