All plain C examples now (mostly) adhere to the curl code style. While they are only examples, they had diverted so much and contained all sorts of different mixed code styles by now. Having them use a unified style helps users and readability. Also, as they get copy-and-pasted widely by users, making sure they're clean and nice is a good idea. 573 checksrc warnings were addressed.

/* <DESC>

* This is a simple example showing how a program on a non-ASCII platform

The IBM-1047 EBCDIC codeset is used for this example but the code
|
|
would be similar for other non-ASCII codesets.
|
|
|
|
Three callback functions are created below:
|
|
my_conv_from_ascii_to_ebcdic,
|
|
my_conv_from_ebcdic_to_ascii, and
|
|
my_conv_from_utf8_to_ebcdic
|
|
|
|
The "platform_xxx" calls represent platform-specific conversion routines.
