Fix body_size_limit negative handling (#838)

When body_size_limit is 0 (either explicitly or implicitly because it
wasn't specified) or less, we are setting it to math.MaxInt64. It turns
out that the implementation in http.MaxBytesReader tries to add 1 to the
specified value, and it wraps around. After that, it tries to use the
result to index an slice, causing it to panic.

Work around this by setting the limit to math.MaxInt64 - 1.

Also, if body_size_limit is exactly 0, leave it like that. That causes
the code to avoid setting up the limiter, saving some extra processing.

Signed-off-by: Marcelo E. Magallon <marcelo.magallon@grafana.com>

Add body_size_limit option to http module (#836)

This option limits the maximum body length that will be read from the
HTTP server. It's meant to prevent misconfigured servers from causing
the probe to use too many resources, even if temporarily. It's not an
additional check on the response, for that, use the resulting metrics
(probe_http_content_length, probe_http_uncompressed_body_length, etc).

Add support for decompression of HTTP responses

Add support for decompression of HTTP responses

If the module configuration specifies the "compression" option
blackbox_exporter will try to decompress the response using the
specified algorithm. If the response is not compressed using that
algorithm, the probe will fail.

It validates that the "Accept-Encoding" header is either absent, or that
it specifies the same algorithm as the "compression" option. If the
"Accept-Encoding" header is present but it specifies a different
algorithm, the probe will fail.

If the compression option is *not* used, probe_http_content_length and
probe_http_uncompressed_body_length will have the same value
corresponding to the original content length. If the compression option
is used and the content can be decompressed, probe_http_content_length
will report the original content length as it currently does, and
probe_http_uncompressed_body_length will report the length of the body
after decompression as expected.
