Since C99, `FLT_EVAL_METHOD` should be left for the compiler/libc to
define. Its redefinition breaks compilation with picolibc as the
target's libc, since it defines said symbol in math.h before the libm
define is evaluated by the compiler.
In its place, there is a check to make sure floating point type sizes
are what are expected to be, triggering a compilation error if those
assumptions are no longer valid.

This updates the berkeley-db-1.xx submodule URL to a repository hosted
under the micropython organisation, and makes the following changes:
- Moves the berkeley-db header files to a single directory within the
submodule, and references all these headers with a much fuller path,
which prevents symbol clashes (eg with esp32 and queue.h).
- Removes unused/non-working files from berkeley-db, which removes all
symlinks in that repo (symlinks don't play well under Windows).
- Allows injecting an external configuration header into berkeley-db, so
the configuration doesn't have to be provided by -Dxx=yy flags to the
compiler (and possibly clashing with other symbols).
- Removes the advertising clause from the BSD 4-clause license of
berkeley-db (see relevant commit and README.Impt.License.Change for
details).

libmetal provides an abstraction of the underlying hardware, to support

OpenAMP framework provides a standard inter processor communications
infrastructure for RTOS and bare metal environments. There are 3 major
components in OpenAMP: libmetal, remoteproc and RPMsg. libmetal provides
abstraction of the low-level underlying hardware, remoteproc is used for
processor Life Cycle Management (LCM) like loading firmware, starting,
stopping a core etc., and RPMsg is a bus infrastructure that enables Inter
Processor Communications (IPC) between different cores.

The primary purpose of this commit is to make decompress default to
wbits=15 when the format is gzip (or auto format with gzip detected). The
idea is that someone decompressing a gzip stream should be able to use the
default `deflate.DeflateIO(f)` and it will "just work" for any input
stream, even though it uses a lot of memory.
This is done by making uzlib report gzip files as having wbits set to 15
in their header (where it previously only set the wbits out parameter for
zlib files), and then fixing up the logic in `deflateio_init_read`.
Updates the documentation to match.

Collapsing the two adjacent calls to outbits saves 32 bytes.
Bringing defl_static.c into lz77.c allows better inlining, saves 24 bytes.
Merge the Outbuf/uzlib_lz77_state_t structs, a minor simplification that
doesn't change code size.

This commit makes the following changes:
- Replace 256-byte reverse-bits-in-byte lookup table with computation.
- Replace length and distance code lookup tables with computation.
- Remove comp_disabled check (it's unused).
- Make the dest_write_cb take the data pointer directly, rather than the
Outbuf.

The compression algorithm implemented in this commit uses much less memory
compared to the standard way of implementing it using a hash table and
large look-back window. In particular the algorithm here doesn't allocate
hash table to store indices into the history of the previously seen text.
Instead it simply does a brute-force-search of the history text to find a
match for the compressor. This is slower (linear search vs hash table
lookup) but with a small enough history (eg 512 bytes) it's not that slow.
And a small history does not impact the compression too much.
To give some more concrete numbers comparing memory use between the
approaches:
- Standard approach: inplace compression, all text to compress must be in
RAM (or at least memory addressable), and then an additional 16k bytes
RAM of hash table pointers, pointing into the text
- The approach in this commit: streaming compression, only a limited amount
of previous text must be in RAM (user selectable, defaults to 512 bytes).
To compress, say, 1k of data, the standard approach requires all that data
to be in RAM, plus an additional 16k of RAM for the hash table pointers.
With this commit, you only need the 1k of data in RAM. Or if it's
streaming from a file (or elsewhere), you could get away with only 256
bytes of RAM for the sliding history and still get very decent compression.
In summary: because compression takes such a large amount of RAM (in the
standard algorithm) and it's not really suitable for microcontrollers, the
approach taken in this commit is to minimise RAM usage as much as possible,
and still have acceptable performance (speed and compression ratio).
