4fbe2b2b5e seq: implement -f FORMAT option
Add support for the `-f FORMAT` option to `seq`. This option instructs
the program to render each value in the generated sequence using a
given `printf`-style floating point format. For example,

    $ seq -f %.2f 0.0 0.1 0.5
    0.00
    0.10
    0.20
    0.30
    0.40
    0.50

Fixes issue #2616.

294bde8e08 seq: correct width for certain negative decimals
Fix a bug in which a negative decimal input would not be displayed with
the correct width in the output. Before this commit, the output was
incorrectly

    $ seq -w -.1 .1 .11
    -0.1
    0.0
    0.1

After this commit, the output is correctly

    $ seq -w -.1 .1 .11
    -0.1
    00.0
    00.1

The code was failing to take into account that the input decimal "-.1"
needs to be displayed with a leading zero, like "-0.1".

0b86afa858 seq: correct fixed-width spacing for inf sequences
Pad infinity and negative infinity values with spaces when using the
`-w` option to `seq`. This corrects the behavior of `seq` to match that
of the GNU version:

    $ seq -w 1.000 inf inf | head -n 4
    1.000
      inf
      inf
      inf

Previously, it incorrectly padded with 0s instead of spaces.

seq: use BigDecimal to represent floats (#2698)
* seq: use BigDecimal to represent floats

Use `BigDecimal` to represent arbitrary precision floats in order to
prevent numerical precision issues when iterating over a sequence of
numbers. This commit makes several changes at once to accomplish this
goal.

First, it creates a new struct, `PreciseNumber`, that is responsible for
storing not only the number itself but also the number of digits (both
integer and decimal) needed to display it. This information is collected
at the time of parsing the number, which lives in the new
`numberparse.rs` module.

Second, it uses the `BigDecimal` struct to store arbitrary precision
floating point numbers instead of the previous `f64` primitive
type. This protects against issues of numerical precision when
repeatedly accumulating a very small increment.

Third, since neither the `BigDecimal` nor `BigInt` types have a
representation of infinity, minus infinity, minus zero, or NaN, we add
the `ExtendedBigDecimal` and `ExtendedBigInt` enumerations which extend
the basic types with these concepts.

2ac5dc0a70 seq: compute correct width for scientific notation
Change the way `seq` computes the number of digits needed to print a
number so that it works for inputs given in scientific notation.
Specifically, this commit parses the input string to determine whether
it is an integer, a float in decimal notation, or a float in scientific
notation, and then computes the number of integral digits and the number
of fractional digits based on that. This also supports floating point
negative zero, expressed in both decimal and scientific notation.

53a91be2df seq: add is_first_iteration to avoid comparisons
Add the `is_first_iteration` Boolean variable to the `print_seq()`
function in order to avoid unnecessary comparisons. Specifically, before
this change, the `done_printing()` function was called twice on each
iteration of the main loop. After this change, it is only called once
per iteration.

Furthermore, this change makes the `print_seq()` function similar in
structure to the `print_seq_integers()` function.

5cd55391ec seq: compute width of numbers after parsing
Fix a bug in `seq` where the number of characters needed to print the
number was computed incorrectly in some cases. This commit changes the
computation of the width to be after parsing the number instead of
before, in order to accommodate inputs like `1e3`, which requires four
digits when printing the number, not three.

1755195251 uu: Replace return_if_err with crash_if_err
Unify the usage of macros `return_if_err` and `crash_if_err`. As
`return_if_err` is used only in `uumain` routines of utilities, it
achieves the same thing as `crash_if_err`, which calls the `crash!`
macro to terminate function execution immediately.

4cf18e96f3 seq: change default value for -t and remove dubious escape sequences
GNU seq does not support -t, but always outputs a newline at the end.
Therefore, our default for -t should be \n.

Also removes support for escape sequences (interpreting a literal "\n"
as a newline). This is not what GNU seq is doing, and unexpected.
