- Abort via progress callback to fail early during parallel transfers.
When a critical error occurs during a transfer (eg --fail-early
constraint) then other running transfers will be aborted via progress
callback and finish with error CURLE_ABORTED_BY_CALLBACK (42). In this
case, the callback error does not become the most recent error and a
custom error message is used for those transfers:
curld --fail --fail-early --parallel
https://httpbin.org/status/404https://httpbin.org/delay/10
curl: (22) The requested URL returned error: 404
curl: (42) Transfer aborted due to critical error in another transfer
> echo %ERRORLEVEL%
22

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.

In particular, these ones can help a user to create its own error
message when one or transfers fail.
writeout: add 'onerror', 'url', 'urlnum', 'exitcode', 'errormsg'
onerror - lets a user only show the rest on non-zero exit codes
url - the input URL used for this transfer
urlnum - the numerical URL counter (0 indexed) for this transfer
exitcode - the numerical exit code for the transfer
errormsg - obvious

The previous sleep for retries would block all other concurrent
transfers. Starting now, the retry will instead be properly marked to
not get restarted until after the delay time but other transfers can
still continue in the mean time.
Closes#5917
- Stick to a single unified way to use structs
- Make checksrc complain on 'typedef struct {'
- Allow them in tests, public headers and examples
- Let MD4_CTX, MD5_CTX, and SHA256_CTX typedefs remain as they actually
typedef different types/structs depending on build conditions.
Closes#5338
Attempt to unpause a busy read in the CURLOPT_XFERINFOFUNCTION.
When uploading from stdin in non-blocking mode, a delay in reading
the stream (EAGAIN) causes curl to pause sending data
(CURL_READFUNC_PAUSE). Prior to this change, a busy read was
detected and unpaused only in the CURLOPT_WRITEFUNCTION handler.
This change performs the same busy read handling in a
CURLOPT_XFERINFOFUNCTION handler.

This is done by making sure each individual transfer is first added to a
linked list as then they can be performed serially, or at will, in
parallel.

- replace tabs with spaces where possible
- remove line ending spaces
- remove double/triple newlines at EOF
- fix a non-UTF-8 character
- cleanup a few indentations/line continuations

To help assist with the detection of incorrect return codes, as per
commits ee23d13a79, 33b8960dc8 and aba98991a5, updated the operate
based functions to return CURLcode error codes.
Configuration files such as curl_config.h and all config-*.h no longer exist
nor are generated/copied into 'src' directory, now these only exist in 'lib'
directory from where curl tool sources uses them.
Additionally old src/setup.h has been refactored into src/tool_setup.h which
now pulls lib/setup.h
The possibility of a makefile needing an include path adjustment exists.
