Move icu4c to separate repository

Browse Source 
Preparation step to build ICU separately for F-Droid builds. Also the
main repo's stats are now not polluted again from the sheer massive
size of ICU.

// Abstract interface that consumes a sequence of bytes (ByteSink).
//
// Used so that we can write a single piece of code that can operate
// on a variety of output string types.
//
// Various implementations of this interface are provided:
// ByteSink:
// CheckedArrayByteSink Write to a flat array, with bounds checking
// StringByteSink Write to an STL string
// This code is a contribution of Google code, and the style used here is
// a compromise between the original Google code and the ICU coding guidelines.
// For example, data types are ICU-ified (size_t,int->int32_t),
// and API comments doxygen-ified, but function names and behavior are
// as in the original, if possible.
// Assertion-style error handling, not available in ICU, was changed to
// parameter "pinning" similar to UnicodeString.
//
// In addition, this is only a partial port of the original Google code,
// limited to what was needed so far. The (nearly) complete original code
// is in the ICU svn repository at icuhtml/trunk/design/strings/contrib
// (see ICU ticket 6765, r25517).

*
* These classes are inspired by
* - std::auto_ptr
* - boost::scoped_ptr & boost::scoped_array
* - Taligent Safe Pointers (TOnlyPointerTo)
*
* but none of those provide for all of the goals for ICU smart pointers:
* - Smart pointer owns the object and releases it when it goes out of scope.
* - No transfer of ownership via copy/assignment to reduce misuse. Simpler & more robust.
* - ICU-compatible: No exceptions.
* - Need to be able to orphan/release the pointer and its ownership.
* - Need variants for normal C++ object pointers, C++ arrays, and ICU C service objects.
*
* For details see http://site.icu-project.org/design/cpp/scoped_ptr

/**
* <code>Replaceable</code> is an abstract base class representing a
* string of characters that supports the replacement of a range of
* itself with a new string of characters. It is used by APIs that
* change a piece of text while retaining metadata. Metadata is data
* other than the Unicode characters returned by char32At(). One
* example of metadata is style attributes; another is an edit
* history, marking each character with an author and revision number.
*
* <p>An implicit aspect of the <code>Replaceable</code> API is that
* during a replace operation, new characters take on the metadata of
* the old characters. For example, if the string "the <b>bold</b>
* font" has range (4, 8) replaced with "strong", then it becomes "the
* <b>strong</b> font".
*
* <p><code>Replaceable</code> specifies ranges using a start
* offset and a limit offset. The range of characters thus specified
* includes the characters at offset start..limit-1. That is, the
* start offset is inclusive, and the limit offset is exclusive.
*
* <p><code>Replaceable</code> also includes API to access characters
* in the string: <code>length()</code>, <code>charAt()</code>,
* <code>char32At()</code>, and <code>extractBetween()</code>.
*
* <p>For a subclass to support metadata, typical behavior of
* <code>replace()</code> is the following:
* <ul>
* <li>Set the metadata of the new text to the metadata of the first
* character replaced</li>
* <li>If no characters are replaced, use the metadata of the
* previous character</li>
* <li>If there is no previous character (i.e. start == 0), use the
* following character</li>
* <li>If there is no following character (i.e. the replaceable was
* empty), use default metadata.<br>
* <li>If the code point U+FFFF is seen, it should be interpreted as
* a special marker having no metadata<li>
* </li>
* </ul>
* If this is not the behavior, the subclass should document any differences.

/**
* \file
* \brief C UConverter predefined error callbacks
*
* <h2>Error Behaviour Functions</h2>
* Defines some error behaviour functions called by ucnv_{from,to}Unicode
* These are provided as part of ICU and many are stable, but they
* can also be considered only as an example of what can be done with
* callbacks. You may of course write your own.
*
* If you want to write your own, you may also find the functions from
* ucnv_cb.h useful when writing your own callbacks.
*
* These functions, although public, should NEVER be called directly.
* They should be used as parameters to the ucnv_setFromUCallback
* and ucnv_setToUCallback functions, to set the behaviour of a converter
* when it encounters ILLEGAL/UNMAPPED/INVALID sequences.
*
* usage example: 'STOP' doesn't need any context, but newContext
* could be set to something other than 'NULL' if needed. The available
* contexts in this header can modify the default behavior of the callback.
*
* \code
* UErrorCode err = U_ZERO_ERROR;
* UConverter *myConverter = ucnv_open("ibm-949", &err);
* const void *oldContext;
* UConverterFromUCallback oldAction;
*
*
* if (U_SUCCESS(err))
* {
* ucnv_setFromUCallBack(myConverter,
* UCNV_FROM_U_CALLBACK_STOP,
* NULL,
* &oldAction,
* &oldContext,
* &status);
* }
* \endcode
*
* The code above tells "myConverter" to stop when it encounters an
* ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
* Unicode -> Codepage. The behavior from Codepage to Unicode is not changed,
* and ucnv_setToUCallBack would need to be called in order to change
* that behavior too.
*
* Here is an example with a context:
*
* \code
* UErrorCode err = U_ZERO_ERROR;
* UConverter *myConverter = ucnv_open("ibm-949", &err);
* const void *oldContext;
* UConverterFromUCallback oldAction;
*
*
* if (U_SUCCESS(err))
* {
* ucnv_setToUCallBack(myConverter,
* UCNV_TO_U_CALLBACK_SUBSTITUTE,
* UCNV_SUB_STOP_ON_ILLEGAL,
* &oldAction,
* &oldContext,
* &status);
* }
* \endcode
*
* The code above tells "myConverter" to stop when it encounters an
* ILLEGAL/TRUNCATED/INVALID sequences when it is used to convert from
* Codepage -> Unicode. Any unmapped and legal characters will be
* substituted to be the default substitution character.

* Miscellaneous switches:
*
* A number of macros affect a variety of minor aspects of ICU.
* Most of them used to be defined elsewhere (e.g., in utypes.h or platform.h)
* and moved here to make them easier to find.
*
* Switches for excluding parts of ICU library code modules:
*
* Changing these macros allows building partial, smaller libraries for special purposes.
* By default, all modules are built.
* The switches are fairly coarse, controlling large modules.
* Basic services cannot be turned off.
*
* Building with any of these options does not guarantee that the
* ICU build process will completely work. It is recommended that
* the ICU libraries and data be built using the normal build.
* At that time you should remove the data used by those services.
* After building the ICU data library, you should rebuild the ICU
* libraries with these switches customized to your needs.

* \brief C API: 16-bit Unicode handling macros

* This file defines macros to deal with 16-bit Unicode (UTF-16) code units and strings.
*
* For more information see utf.h and the ICU User Guide Strings chapter
* (https://unicode-org.github.io/icu/userguide/strings).
*
* <em>Usage:</em>
* ICU coding guidelines for if() statements should be followed when using these macros.
* Compound statements (curly braces {}) must be used for if-else-while...

* For more information see utf.h and the ICU User Guide Strings chapter

* Compound statements (curly braces {}) must be used for if-else-while...
