(cherry picked from commit 21843d0)

(cherry picked from commit 3870614)

* Fix a handful of invalidations in expression-checking (#138)

ChainRulesCore defines `==(a, b::AbstractThunk)` and its converse,
and this invalidates a couple of poorly-typed Symbol checks.
This more "SSA-like" way of writing the code is easier to infer.

(cherry picked from commit 25f7af3)

* tests: skip wrong host test for SSL_NO_VERIFY (fix #139) (#140)

Since #114, we only turn
off peer verification, not host verification when the `SSL_NO_VERIFY`
variables are set. This means that the last set of tests in the "SSL no
verify override" testset *should* fail for `wrong.host.badssl.com`. That
is not what I was seeing, however — the test was still passing — which I
found puzzling but just moved on with my life at the time. It turns out
that the test *does* fail if libcurl is build with OpenSSL. Since
whether the test passes or not for that host depends on how things are
built, this change simply skips the test (by popping the URL from the
set of tested URLS for that testset).

The tests above that which use the easy hook mechanism are fixed in a
different way: for those I made the hook disable both host and peer
verification, which should fix the tests for any bad host including when
the server sends the wrong host name.

* Fix input body size detection for IOBuffer(codeunits(str)) (#143)

Somewhat surprisingly, the type of this is not IOBuffer, but a related
type (Base.GenericIOBuffer{Base.CodeUnits{UInt8, String}}).

(cherry picked from commit 43a3484)

* fix Timer usage (#158)

(cherry picked from commit 62b497e)

* Workaround for missing isopen check in FDWatcher (#161)

(possible multithread race with this still needs to be fixed)

(cherry picked from commit 7f91b8a)

* Check for timer isopen correctly (#162)

(cherry picked from commit 4250b35)

* remove trailing whitespace

(cherry picked from commit d8c626b)

* Avoid infinite recursion in `timer_callback` (#164)

Fixes #163

(cherry picked from commit a55825b)

* should also look into headers for input_size (#167)

If no content length is set while uploading some contents, Curl defaults to use
chunked transfer encoding. In some cases we want to prevent that because the
server may not support chunked transfers.

With this change, the request method will also look at the headers while
determining the input size and if found call `set_upload_size` as usual. So to
switch off chunked transfers, one must also know and set the content length
header while invoking `download` or `request` methods.

(cherry picked from commit ab628ab)

* rename: singularize add_{upload,seek}_callback

These only add one callback so having them be plural is weird.

(cherry picked from commit 5bd0826)

* add support for setting a debug callback

(cherry picked from commit 55a0c39)

* end-to-end tests for #167

This adds end-to-end tests for the changes introduced in #167.

Verbose mode is switched off for these tests, but switching it on would show that not setting content-length headers results in chunked transfer encoding while setting it prevents that. Both tests should pass.

(cherry picked from commit 911368d)

* tests: use debug option to test for non/chunked uploads

This combines the functionality from the previous two commits to not
only trigger both chunked and non-chunked uploads, but also test for
that difference by capturing and inspecting the debug events.

(cherry picked from commit 4e0408a)

* bump patch
