urlapi: leaner with fewer allocs
Slightly faster with more robust code. Uses fewer and smaller mallocs.

- remove two fields from the URL handle struct
- reduce copies and allocs
- use dynbuf buffers more instead of custom malloc + copies
- uses dynbuf to build the host name in reduces serial alloc+free within
  the same function.
- move dedotdotify into urlapi.c and make it static, not strdup the input
  and optimize it by checking for . and / before using strncmp
- remove a few strlen() calls
- add Curl_dyn_setlen() that can "trim" an existing dynbuf

multi: use larger dns hash table for multi interface
Have curl_multi_init() use a much larger DNS hash table than used for
the easy interface to scale and perform better when used with _many_
host names.

curl_share_init() sets an in-between size.

base64: base64url encoding has no padding
See RFC4648 section 5 and RFC7540 section 3.2.1.

Suppress generation of '=' padding of base64url encoding. This is
accomplished by considering the string beginning at offset 64 in the
character table as the padding: this is "=" for base64, "" for base64url.

Also use strchr() to replace character search loops where possible.

Suppress erroneous comments about empty encoding results.

Adjust unit test 1302 to unpadded base64url encoding and add tests for
empty results.

6019d652b5 unit1620: call global_init before calling Curl_open
Curl_open calls the resolver init and on Windows if the resolver backend

configure: remove support for "embedded ares"
In March 2010 (commit 4259d2df7d) we removed the embedded 'ares'
directory from the curl source tree but we have since supported
especially detecting and using that build directory. The time has come
to remove that kludge and ask users to specify the c-ares dir correctly
with --enable-ares.

infof: remove newline from format strings, always append it
- the data needs to be "line-based" anyway since it's also passed to the

- it makes infof() work like failf() and consistency is good

- Removes the code that would append "..." to the end of the data *iff*
  it was truncated in infof()

metalink: remove
Warning: this will make existing curl command lines that use metalink to
stop working.

Reasons for removal:

1. We've found several security problems and issues involving the
   metalink support in curl. The issues are not detailed here. When
   working on those, it become apparent to the team that several of the
   problems are due to the system design, metalink library API and what
   the metalink RFC says. They are very hard to fix on the curl side
   only.

2. The metalink usage with curl was only very briefly documented and was
   not following the "normal" curl usage pattern in several ways, making
   it surprising and non-intuitive which could lead to further security
   issues.

3. The metalink library was last updated 6 years ago and wasn't so
   active the years before that either. An unmaintained library means
   there's a security problem waiting to happen. This is probably reason
   enough.

4. Metalink requires an XML parsing library, which is complex code (even
   the smaller alternatives) and to this day often gets security
   updates.

5. Metalink is not a widely used curl feature. In the 2020 curl user
   survey, only 1.4% of the responders said that they'd are using it. In
   2021 that number was 1.2%. Searching the web also show very few
   traces of it being used, even with other tools.

6. The torrent format and associated technology clearly won for
   downloading large files from multiple sources in parallel.

bufref: buffer reference support
A struct bufref holds a buffer pointer, a data size and a destructor.
When freed or its contents are changed, the previous buffer is implicitly
released by the associated destructor. The data size, although not used
internally, allows binary data support.

A unit test checks its handling methods: test 1661

lib: pass in 'struct Curl_easy *' to most functions
... in most cases instead of 'struct connectdata *' but in some cases in
addition to.

- We mostly operate on transfers and not connections.

- We need the transfer handle to log, store data and more. Everything in
  libcurl is driven by a transfer (the CURL * in the public API).

- This work clarifies and separates the transfers from the connections
  better.

- We should avoid "conn->data". Since individual connections can be used
  by many transfers when multiplexing, making sure that conn->data
  points to the current and correct transfer at all times is difficult
  and has been notoriously error-prone over the years. The goal is to
  ultimately remove the conn->data pointer for this reason.
