Right now cbmem uses a fix path to reach coreboot src path (../../).
This makes it impossible to compile cbmem out of the coreboot tree (e.g.
copy just the cbmem directory elsewhere and compile).
This patch adapts the technique from cbfstool and adds a variable called
'TOP' which points to coreboot root directory and which can be
overridden at build time by providing it to make as an argument. This
will enable a stand-alone build of cbmem.

Since the new loglevel markers were added, there will now be a marker
character at the beginning of the coreboot banner string, and this will
make the existing regular expressions meant to find it fail to match.
This patch fixes the problem by just allowing for a single extra
character there (any character to avoid the hassle of having to match
the marker explicitly). The extra character is optional so that we will
still continue to match banners from older versions of coreboot as well.
Since the `?` glyph is not available in basic POSIX regular expressions,
we have to switch to REG_EXTENDED syntax (should otherwise make no
difference). (Also, move side effects out of assert() while I'm here,
that's not actually safe for the standard libc implementation.)

This patch adds a new --loglevel option to the CBMEM utility which can
be used either numerically (e.g. `cbmem -1 --loglevel 6`) or by name
(e.g. `cbmem -c --loglevel INFO`) to restrict the lines that will be
printed from the CBMEM console log to a maximum loglevel. By default,
using this option means that lines without a loglevel (which usually
happens when payloads or other non-coreboot components add their own
logs to the CBMEM console) will not be printed. Prefixing a `+`
character to the option value (e.g. `--loglevel +6` or
`--loglevel +INFO`) can be used to change that behavior.

In order to provide the same loglevel prefixes and highlighting that
were recently introduced for "interactive" consoles (e.g. UART) to
"stored" consoles (e.g. CBMEM) but minimize the amont of extra storage
space wasted on this info, this patch will write a 1-byte control
character marker indicating the loglevel to the start of every line
logged in those consoles. The `cbmem` utility will then interpret those
markers and translate them back into loglevel prefixes and escape
sequences as needed.
Since coreboot and userspace log readers aren't always in sync,
occasionally an older reader may come across these markers and not know
how to interpret them... but that should usually be fine, as the range
chosen contains non-printable ASCII characters that normally have no
effect on the terminal. At worst the outdated reader would display one
garbled character at the start of every line which isn't that bad.
(Older versions of the `cbmem` utility will translate non-printable
characters into `?` question marks.)

On some platforms, runtime firmware crashes write logs to the CBMEM

have a chance to run `cbmem` again the boot where the crash happened

show the interesting part, and cbmem -c potentially shows a lot that is
cumbersome to dig through. This patch introduces a new option cbmem -2
to explicitly show only the boot cycle before the last one.

This patch creates a new commonlib/bsd subdirectory with a similar
purpose to the existing commonlib, with the difference that all files
under this subdirectory shall be licensed under the BSD-3-Clause license
(or compatible permissive license). The goal is to allow more code to be
shared with libpayload in the future.
Initially, I'm going to move a few files there that have already been
BSD-licensed in the existing commonlib. I am also exracting most
contents of the often-needed <commonlib/helpers.h> as long as they have
either been written by me (and are hereby relicensed) or have an
existing equivalent in BSD-licensed libpayload code. I am also
relicensing <commonlib/compression.h> (written by me) and
<commonlib/compiler.h> (same stuff exists in libpayload).
Finally, I am extracting the cb_err error code definitions from
<types.h> into a new BSD-licensed header so that future commonlib/bsd
code can build upon a common set of error values. I am making the
assumption here that the enum constants and the half-sentence fragments
of documentation next to them by themselves do not meet the threshold of
copyrightability.

compare_timestamp_entries will fail for entries that are different by
at least 2^32 since entry_stamp is 64-bit and the return for compare
is 32-bit. This change fixes compare_timestamps by actually comparing
the entries to return 1, -1 or 0 instead of doing math on them.
TEST=Verified that "cbmem -t" sorts entries correctly on previously
failing entries.

If the timestamp entries are added out of order, the duration
calculation will be wrong.
AGESA collects timestamp data through all the stages. Then in AmdInitPost
it asks for a buffer to write TP_Perf_STRUCT into. agesawrapper will then
take the data and call timestamp_add on each entry. This results in
the entries being out of order.
TEST=Built firmware for grunt that manually added entries and then ran
cbmem -t/-T to verify the entries were in the correct order.

In case of console dump for only the last boot, cbmem utility checks
for a list of regex in provided order. When pre-cbmem console
overflows, "Pre-CBMEM <stage> console overflowed.. " message is added
before "... <stage> starting" message. This change fixes the order of
regex in cbmem utility to match this.
Test=Verified on soraka that "cbmem -1" correctly dumps the data
starting from Pre-CBMEM romstage overflowed.

The cbmem utility has inherited some workarounds that originated
from the default 1 MiB mapping always working. This 1 MiB mmap
won't necessarily succeed if the 1 MiB encroaches on a subsequent
memory range that has different cacheability.
To fix this, map in only 4 KiB when the table size is not known which is
the case for any forwarding entry or any low table entries on x86. That
smaller mapping is then searched for a valid header. Once a valid header
is found the full table is mapped and parsed allowing a forwarding entry
to take precedence.
Lastly, the lbtable is kept mapped in such that other operations can
just operate on mapping that was previously parsed.
In order to allow multiple in-flight mappings a struct mapping was
added which caused the ripple within the code. However, there shouldn't
be any more reasons for putting weird heuristics for when to fail. If
the tables are bad then it's very much possible that mappings will fail.
Retrying when the exact sizes are already known won't fix those issues.
