The `fs.readfile()` and `fs.writefile()` functions allow efficient reading
and writing of whole files, reducing the required boilerplace code compared
to using the `open()`/`read()`/`write()`/`close()` API.
- `fs.readfile()` takes two arguments; the path to open and an optional
limit value. If limit is omitted, `null` or negative, the entire file
contents are read, otherwise the specified amount of bytes. Returns the
read file contents as string or `null` on error.
- `fs.writefile()` takes three arguments; the path to open/create, the
contents to write and an optional limit value. If limit is omitted, the
entire content is written, otherwise just the specified amount of bytes.
Non-string content arguments are internally converted to strings, `null`
is treated as empty string. Returns the amount of bytes written or `null`
on error.

fs: fix off-by-one in fs.dirname() function
|
|
Debian package build
|
|
Make sure fs.dirname() doesn't truncate the last character of the
returned path. Previously ucv_string_new_length was called with a
length which no longer included the last character (which had just
been tested not to be a '/' or '.' and hence broke the loop at that
point).

Treat the char value as unsigned when testing its value to yield consistent
results on both platforms with signed chars and those with unsigned chars
by default (e.g. ARM ones). This also avoids encoding byte values > 127 as
\uXXXX escape sequences, potentially breaking the strng contents.

lib: add date and time related functions
|
|
Add five new functions to deal with date calculation and timing:
- localtime(), gmtime() - return a broken down calendar date and time
specification from the given epoch (or now, if absent) in local and
UTC time respectively
- timelocal(), timegm() - the inverse operation for the former functions,
taking a date and time specification (interpreted as local or UTC time
respectively) and turning it into an epoch value
- clock() - return the second and nanosecond values of the system clock,
useful for time/performance measurements

lib: provide API function to obtain stdlib function implementations
|
|
Provide a new API function `uc_stdlib_function()` which allows to fetch
the C implementation of the given named standard library function.
This is useful for loadable modules or applications that embed ucode which
want to reuse core functions such as `sprintf()`.

Tasks are similar to processes but instead of executing a new process, an
ucode function is invoked instead, running independently of the main
process.
Example usage:
uloop.init();
let t = uloop.task(
// program function
function(pipe) {
let input = pipe.receive();
pipe.send({ got_input: input });
return { result: true };
},
// parent recv function, invoked when task function calls pipe.send()
function(res) {
printf("Received output message: %.J\n", res);
},
// parent send function, invoked when task function calls pipe.receive()
function() {
let input = { test: "Example" };
printf("Sending input message: %.J\n", input);
return input;
}
);
uloop.run();

Identifiers starting with one or two underscores are reserved for system
headers and toolchain implementations and should not appear in user code.
Also on OS X, the ucode __TYPES_H_ guard clashes with the system types.h
header. Rename all ucode header guards to avoid such clashes.

- Change command line flags to be align better with those of other
interpreters and with the gcc compiler, e.g. `-D` and `-U` to
define and undefine globals, `-e` to execute script expression etc.
- Pass only excess CLI arguments as `ARGV` to scripts, e.g.
`ucode -e 'print("Hello world")' -- -x -y` would pass only
`[ "-x", "-y" ]` as ARGV contents
- Default to raw mode and introduce flag to enable template mode

lib: fix potential integer underflow on empty render output
|
|
The current `uc_render()` implementation uses a `fseek()` call on the
`open_memstream()` provided `FILE *` stream to reserve headroom for the
`uc_string_t` header. The `fseek()` call alone does not guarantee that
the underlying buffer length is updated on all libc implementations though.
This may lead to an integer underflow later on when the `uc_string_t`
header length is substracted from the buffer length after invoking a
template that did not produce any output write operations. In such a
case, a very large value is assigned to `ustr->length` leading to
uninitialized or out-of-bounds memory accesses later on.
Solve this issue by writing the header structure as data using `fwrite()`
which should yield the expected behaviour on all libc environments.
