This should again enable crazy-large download ranges of the style
[1-10000000] that otherwise easily ran out of memory starting in 7.66.0
when this new handle allocating scheme was introduced.

They serve very little purpose and mostly just add noise. Most of them
have been around for a very long time. I read them all before removing
or rephrasing them.

The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than
it actually does. A different function name makes this easier to detect.

This enables level 4 instead of the default level 3, which of the
currently used comments only allows /* FALLTHROUGH */ to silence the
warning.

- Get rid of variable that was generating false positive warning
(unitialized)
- Fix issues in tests
- Reduce scope of several variables all over
etc
Closes#2631
The multiply() function that is used to avoid integer overflows, was
itself reason for a possible division by zero error when passed a
specially formatted glob.

Prior to this change we depended on errno if strtol could not perform a
conversion. POSIX says EINVAL *may* be set. Some implementations like
Microsoft's will not set it if there's no conversion.

- Add unit test 1604 to test the sanitize_file_name function.
- Use -DCURL_STATICLIB when building libcurltool for unit testing.
- Better detection of reserved DOS device names.
- New flags to modify sanitize behavior:
SANITIZE_ALLOW_COLONS: Allow colons
SANITIZE_ALLOW_PATH: Allow path separators and colons
SANITIZE_ALLOW_RESERVED: Allow reserved device names
SANITIZE_ALLOW_TRUNCATE: Allow truncating a long filename
- Restore sanitization of banned characters from user-specified outfile.
Prior to this commit sanitization of a user-specified outfile was
temporarily disabled in 2b6dadc because there was no way to allow path
separators and colons through while replacing other banned characters.
Now in such a case we call the sanitize function with
SANITIZE_ALLOW_PATH which allows path separators and colons to pass
through.

The glob_range function used wrong offset (3 instead of 4) for parsing
integer step inside character range specification, which led to 'bad
range' error when using character ranges with explicitly specified step
(such as '[a-z:2]')
There was a mix of GlobCode, CURLcode and ints and they were mostly
passing around CURLcode errors. This change makes the functions use only
CURLcode and removes the GlobCode type completely.
By counting from 0 and up instead of backwards like before, we remove
the need for the "funny" check of the unsigned variable when decreased
passed zero. Easier to read and less risk for compiler warnings.
The >= 0 is actually not required, since i underflows and
the for-loop is stopped using the < condition, but this
makes the VS2012 compiler and code analysis happy.
This makes it possible to fetch from an IPv6 literal without specifying
the -g option. Globbing remains available elsehwere in the URL.
For example:
curl http://[::1]/file[1-3].txt
This creates no ambiguity, because there is no overlap between the
syntax of valid globs and valid IPv6 literals. Globs contain hyphens
and at most 1 colon, while IPv6 literals have no hyphens, and at least 2
colons.
The peek_ipv6() parser simply whitelists a set of characters and counts
colons, because the real validation happens later on. The character set
includes A-Z, in case someone decides to implement support for scopes
like [fe80::1%25eth0] in the future.

The "fixed string" function wrongly bumped the "urlnum" counter which
made curl output the total number of URLs wrong when using
{one,two,three} lists in globs.
