Dmitry Frank 23122b327c Remove old docs, rename docs_new to docs
It would be probably good idea to also remove tools/docgen.py and
asciidoc.mk, but asciidoc.mk is still mentioned under `cloud/doc`, which
may contain some useful info which we'll need at least to review before
removing.

- `MG_MALLOC`, `MG_CALLOC`, `MG_REALLOC`, `MG_FREE` allow to use custom
memory allocator, e.g. `-DMG_MALLOC=my_malloc`
- `MG_USE_READ_WRITE` when set replaces calls to `recv` with `read` and `send` with `write`,
thus enabling to add any kind of file descriptor (files, serial devices) to an event manager.
- `MG_SSL_CRYPTO_MODERN`, `MG_SSL_CRYPTO_OLD` - choose either "Modern" or "Old" ciphers
instead of the default "Intermediate" setting.
