A few wifi changes and VFS support for directory-related functions.

Now it also tries to find the included file relatively to the "parent"
file. This is required for amalgamation of the frozen into mjs, since
`frozen.c` includes `frozen.h` instead of `frozen/frozen.h`.

- LWIP UDP sockets are always writable and they are not reported as
such by select() (bug? featuyre?). TCP sockets are ok.
- Always deliver MG_EV_POLL, whether we have other fd_events or not.
Otherwise MG_EV_POLL would not be delivered at all to perma-writable
UDP sockets (as they are on LWIP).
- Ignore EAGAIN/EWOULDBLOCK errors while connecting, this happens
during SSL handshake.

Factor out common part of SPIFFS libc interface support from the CC3200
port and reuse it for ESP32. Minor cleanups.

Namely, define it if only `MG_ENABLE_HTTP_STREAMING_MULTIPART` and
`MG_ENABLE_FILESYSTEM` are on

And use it for `FW_ARCHITECTURE`. This is needed because with
Microchip's xc32, `-DFOO=\"bar\"` results in `FOO` being `bar`, not
`"bar"`, so we have to stringify differently.

Assume handshake request was declined if either MG_F_CLOSE_IMMEDIATELY _or_ MG_F_SEND_AND_CLOSE is set.

Renegotiation is disabled, so we don't need them.
Reduces per-connection usage when idle by 3K.

- Only allow one TCP segment in flight. Each segment is 1.5K and it
adds up. This may increase latency, but memory is precious on ESP.
At teh same time, optimize use of tcp_output: do not send a new segment
on every write, only call tcp_output at the end of connection
processing during poll.
- Build LWIP with DNS disabled. We have our won resolver, and LWIP's
allocates large static buffers (1K).
- mbedTLS: Deallocate peer's certificate at the end of SSL handshake,
reduces idle SSL connection footprint by ~1.5K.
Some tweaks to the heap log viewer (which made all the above possible).

Also performs trnasparent SPIFFS -> SLFS cert copy.
If the file's extension is .pem, convert it to DER format and put on SLFS.
