[mod] py: remove uvloop (#5220)
We get some good stuff without uvloop, 13MB~ less of dependencies, 3
minutes of build time for armv7 saved, and we are one step closer to NT
compatibility. Although it's true that theoretically the raw performance
have worsened on network side (we only used uvloop for that), the latest
cpython versions have been improving on asyncio performance.

57b9673efb [mod] addition of various type hints / tbc
- pyright configuration [1]_
- stub files: types-lxml [2]_
- addition of various type hints
- enable use of new type system features on older Python versions [3]_
- ``.tool-versions`` - set python to lowest version we support (3.10.18) [4]_:
  Older versions typically lack some typing features found in newer Python
  versions.  Therefore, for local type checking (before commit), it is necessary
  to use the older Python interpreter.

542f7d0d7b [mod] pylint all files with one profile / drop PYLINT_SEARXNG_DISABLE_OPTION
In the past, some files were tested with the standard profile, others with a
profile in which most of the messages were switched off ... some files were not
checked at all.

- ``PYLINT_SEARXNG_DISABLE_OPTION`` has been abolished
- the distinction ``# lint: pylint`` is no longer necessary
- the pylint tasks have been reduced from three to two

  1. ./searx/engines -> lint engines with additional builtins
  2. ./searx ./searxng_extra ./tests -> lint all other python files

8fa54ffddf [mod] Shuffle httpx's default ciphers of a SSL context randomly.
From the analyse of @9Ninety [1] we know that DDG (and may be other engines / I
have startpage in mind) does some kind of TLS fingerprint to block bots.

This patch shuffles the default ciphers from httpx to avoid a cipher profile
that is known to httpx (and blocked by DDG).

[1] https://github.com/searxng/searxng/issues/2246#issuecomment-1467895556

----

From `What Is TLS Fingerprint and How to Bypass It`_

> When implementing TLS fingerprinting, servers can't operate based on a
> locked-in whitelist database of fingerprints.  New fingerprints appear
> when web clients or TLS libraries release new versions. So, they have to
> live off a blocklist database instead.
> ...
> It's safe to leave the first three as is but shuffle the remaining ciphers
> and you can bypass the TLS fingerprint check.

32e8c2cf09 searx.network: add "verify" option to the networks
Each network can define a verify option:
* false to disable certificate verification
* a path to existing certificate.

SearXNG uses SSL_CERT_FILE and SSL_CERT_DIR when they are defined

e64c3deab7 [mod] upgrade httpx 0.21.2
httpx 0.21.2 and httpcore 0.14.4 fix multiple issues:
* https://github.com/encode/httpx/releases/tag/0.21.2
* https://github.com/encode/httpcore/releases/tag/0.14.4

so most of the workarounds in searx.network have been removed.

443bf35e09 [pylint] fix global-variable-not-assigned issues
If there is no write access, there is no need for global.  Remove global
statement if there is no assignment.

global-variable-not-assigned:
  Using global for names but no assignment is done Used when a variable is
  defined through the "global" statement but no assignment to this variable is
  done.

In Pylint 2.11 the global-variable-not-assigned checker now catches global
variables that are never reassigned in a local scope and catches (reassigned)
functions [1][2]

d14994dc73 [httpx] replace searx.poolrequests by searx.network
settings.yml:

* outgoing.networks:
   * can contains network definition
   * propertiers: enable_http, verify, http2, max_connections, max_keepalive_connections,
     keepalive_expiry, local_addresses, support_ipv4, support_ipv6, proxies, max_redirects, retries
   * retries: 0 by default, number of times searx retries to send the HTTP request (using different IP & proxy each time)
   * local_addresses can be "192.168.0.1/24" (it supports IPv6)
   * support_ipv4 & support_ipv6: both True by default
     see https://github.com/searx/searx/pull/1034
* each engine can define a "network" section:
   * either a full network description
   * either reference an existing network

* all HTTP requests of engine use the same HTTP configuration (it was not the case before, see proxy configuration in master)
